Methanesulfonamide → N-{4-[15-(Trifluoromethyl)pentadecylamino]-benzoyl}methanesulfonamide

Participants

Reaction Steps

A solution of 25.2 g. of 4-[15-(trifluoromethyl)-pentadecylamino]benzoyl chloride hydrochloride and 5.6 g. of methanesulfonamide in 250 ml. of pyridine is stirred under reflux for 2 hours and then concentrated in vacuo. The residue is partitioned between water and diethyl ether; the aqueous layer acidified with 1 N hydrochloric acid, and the organic layer separated, dried over magnesium sulfate and evaporated. Crystallization of the residual white solid from 60% aqueous acetic acid and then from methylene chloride-hexane affords the product as a white solid.
