Maybe just rent a helium tank from a party supply store?

They add oxygen so the little suckers don't pass out.. just an FYI

The cheapest I had seen there worked out to 12-15/g and I figured a working quantity was around 10g so my cursory estimation was a bit on the high side, but any fuck-ups will start adding up pretty quickly.

I had no idea about the oxygen in the helium.  I had always figured it was a viable replacement for nitrogen blankets.

Most grignard reagents need to be kept separate from the air, but don't require too much special care because they're formed in ether or similar, which is so volatile that it creates a protective vapor blanket.  Maybe a similar effect could be achieved by using a more volatile solvent for the organolithium formation.

we are now disussing metalation with lithium metal
it will form the aryl lithium, an alkoxide at the OH and, upon quenching we have dechlorinated product.

also there are organolithium  coumpounds with amide functions on them whether they were specifically prepared in this manner, i can't comment, that would warrant further investigation.
pondering the subject of base induced enolization of the dimethylamido moiety i realized that the O atom is electron rich because of the neighboring methylgroups.
additionally the alphacarbon to the amide is bonded to two benzene rings imparting further electron density via sigma bond induction.
which makes this even less prone to proton abstraction, enolization, followed by some weird radical polymer chemistry: which is probably beyond my comprehension.
afterall, i'm just a lowly unemployed construction worker, what would i know?

right because see the alkyl lithium is producing an orgonolithium amide another organic base because the prim and sec amides have protons this is a special case.
 i say it's a green light,  GO!!!

metal hydridrides work also but that's being very vaugge oh let me gather my senses i have a few references.

i think it's easiest to bang it up with some lithium in a sonication bath really don't have to prepare anything it's just mix and go it would be wise to esterify the OH first then do the metallation but the exotherm from the formation of the alkoxide might drive the reaction too see.
because they require a little energy of activation to get going.
nah it's smarter to esterify that OH sonicate monitor temps and when the induction is up and the exotherm kicks in let it go then heat for a few more hours spot it on tlc to judge completion.
that's most logical i think they like to run in the 50 C range

im realy starting to like the idea of using pd/c as well as it will work as both an oxidizing agent and a reducing agent.

works real well for acid to I bet.

you mean a gringnard alkylation??? like rmgX + aryl CL = r aryl?
it's possible but why go through the elbow just to get to your asshole because that would be a tricky reaction to actually pull off.
when you can just "bang it with lithium and then hydrolyse it very carefully mind you under a protective blanket with 10% HCl @ 0 C)
exothermic, hydrogen gas is generated keep that in mind)

if it will strip chloro it will snip bromo off with ease.

Argon is the best gas for blanketing oxygen sensitive reactions, because it's inert and very dense  Members of Hyperlab have successfully used hydrocarbons such as propane, but it's inherently more dangerous because it's flammable  Helium is inert but not very dense Nitrogen can be made from compressed air:

Air freed from carbon dioxide in a wash bottle of sodium hydroxide, A, and from moisture by passage through sulphuric acid, B, is then passed through a red-hot tube containing copper turnings. The copper removes the oxygen and forms cupric oxide 2Cu+02=2CuO. The nitrogen passes on to be collected in a gas jar, or gasholder, etc. In the diagram, the air is supposed to be drawn over the copper, the gasholder being filled with nitrogen. If the gasholder were placed at the end A, and air forced along the tubes, the nitrogen gas could be collected in gas jars. Cold boiled water should be, used in the gasholder so as to lessen the risk of contamination owing to the presence of oxygen dissolved in ordinary water.

this is done in molten sodium???
no way that willnot work i donnot belive to harsh conditions.
