Reaction Steps

A mixture of 5-(2-fluoro-4-methanesulfonyl-phenyl)-2-piperidin-4-yl-furo[2,3-c]pyridine (80 mg), methanesulfonic acid 1-trifluoromethyl-cyclopropylmethyl ester (120 mg), KI (21 mg), K2CO3 (92 mg), and N-methylpyrrolidinone (3 mL) is stirred at 100° C. for 4 h. After cooling to room temperature, water is added and the mixture is extracted with ethyl acetate. The combined extracts are dried (Na2SO4) and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 4:1→1:1) to give the title compound. Mass spectrum (ESI+): m/z=497 [M+H]+.
