Triethylamine → {4-[(3-Sulfonylmethylpyridyl)amino]-2-phenylbenzoyl}methionine methyl ester

Participants

Reaction Steps

A mixture of 3-chlorosulfonylmethylpyridine hydrochloride (1.0 equivalent) and (4-amino-2-phenylbenzoyl)methionine methyl ester (1.0 equivalent) in dichloromethane is treated with triethylamine (2.2 equivalents). When judged complete by TLC analysis, the reaction is diluted with ethyl acetate, and then is washed with pH 4 water, saturated NaHCO3, and brine. The mixture is dried and concentrated to give the crude title compound which is purified by chromatography on silica gel.
