[2,4-Dimethyl-6-(3-trifluoromethoxy-phenyl)-pyridin-3-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone → benzoic acid (S)-1-{1-[2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-pyridine-3-carbonyl]-piperidin-4-yl}-pyrrolidin-2-ylmethyl ester

Reaction Steps

In analogy to the procedures described for intermediate 1 and for intermediate 4B,2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-nicotinic acid (example 28) was converted into its acid chloride and reacted with benzoic acid (S)-1-piperidin-4-yl-pyrrolidin-2-ylmethyl ester (intermediate 3) to give benzoic acid (S)-1-{1-[2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-pyridine-3-carbonyl]-piperidin-4-yl}-pyrrolidin-2-ylmethyl ester, which was subsequently saponified to give the title compound as colorless amorphous solid. MS: 478.2 (MH+).
