Hi!
Swim had this dream today, that he reduced 21g slightly brown 2,5-DMNS, using 16.8 g LAH in lots of THF. Because of a slight problem with dissolving the NS in IPA, it was not as pure as the other runs. The reduced THF soln. was dark green and not yellowish as i was on the other runs? Swim supposes that it does not matter and the discoloration is just something that will be removed during A/B wash. Will slightly dirty NS ruin the reaction? Swim was under the impression, that LAH was quite selective and the product wil be 10-4?
Thanks!
Regards Peter
