OTC methylating agent from hybrid mustard agent?

[Lestat]

Had a bit of a brainfart here and I am wondering if anybee would be able to make something of this?

Thiodyglycol seperated from ballpen ink, most likely by either distillation or filtration,

HCl gassing of seperated thiodyglycol to produce
bis(2-chloroethyl)sulfide (sulfur mustard)

Addittion of methylamine (or any other suitable chemical you beez can dream up).

This SHOULD produce a hybrid agent between type one nitrogen mustard which has an ethylamine instead of the sulfur group on simple sulfur mustard, and ziakov mustard which has instead, a methyl group.

This would be one heck of an alkylating agent would it not?
of course, mustards are, on the whole, notorious for just that.

And if this isn't useful to any bees, at least they can have some fun with a nice OTC blister agent recipe
