Procedure
To a solution of 2-[3-(4-carboxybenzyloxycarbonylamino)-2-oxo-6-phenyl-1,2-dihydro-1-pyridyl]-N-(3,3,3-trifluoro-1-isopropyl-2-oxopropyl)acetamide (0.387 g), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.43 g) and 4-dimethylaminopyridine (0.27 g) in dry dichloromethane was added methanesulfonamide; and the reaction mixture was stirred for 5 days. The mixture was diluted with ethyl acetate, washed (three times with 10% aqueous hydrochloric acid, then brine), dried and evaporated before purification by chromatography, eluting with dichloromethane:ethyl acetate:methanol:acetic acid (50:48.9:1.0:0.1), to give the title compound; TLC: Rf =0.38, dichloromethane:ethyl acetate:methanol:acetic acid (50:48.9:1.0:0.1); HPLC: tR =5.38, FR=2, column A, water:acetonitrile (7:3); MS: m/z=651(M+1).
