Participants

Reaction Steps

90 mg (0.2 mmol) of N-[(1S)-2-amino-1-(5-chloro-1H-benzimidazol-2-yl)ethyl]-3-methyl-4-(pyrrolidin-1-ylcarbonyl)benzamide is placed in 2 mL of dichloromethane, combined with 0.03 g (0.25 mmol) of triethylamine and while being cooled in the ice bath combined with 0.03 g (0.23 mmol) of methanesulfonic acid chloride. Then the mixture is heated to ambient temperature and stirred for 24 hours. Then the solvent is eliminated in vacuo and the residue purified by chromatography on silica gel (gradient: dichloromethane/methanol=100:5). Yield: 27 mg (25%); Rf value: 0.20 (silica gel; dichloromethane/methanol=95:5); C23H26ClN5O4S (504.01); mass spectrum: (M+H)+=504/506 (chlorine isotope).
