1-(3,4,5-Trimethoxybenzoyl)-3-(phenylmethyl)-3-(2-methanesulfonyloxyethyl)pyrrolidine → 1-(3,4,5-trimethoxybenzoyl)-3-(2-(4-(1H-benzimidazol-2-yl-amino)piperidin-1-yl)ethyl)-3-(phenylmethyl)pyrrolidine

Participants

Reaction Steps

Prepare by the method of Example 4.1 using 1-(3,4,5-trimethoxybenzoyl)-3-(phenylmethyl)-3-(2-methanesulfonyloxyethyl)pyrrolidine (0.8 g, 1.67 mmol) and (1H-benzimidazol-2-yl)(piperidin-4-yl)amine hydriodic acid salt (0.8 g, 1.67 mmol). Purify by chromatography on silica gel eluting with 2% triethylamine/30% methanol/ethyl acetate to give the title compound: Rf=0.21 (silica gel, 2% triethylamine/30% methanol/ethyl acetate).
