Versuchsvorschrift
A solution of 25.2 g. of 3-fluoro-4-(hexadecylamino)-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 HCl, and the organic layer separated, dried (MgSO4), and evaporated. Crystallization of the residual white solid from 60% aqueous acetic acid and then from methylene chloride-hexane affords N-[3-fluoro-4-(hexadecylamino)benzoyl]methanesulfonamide as a white solid.
