Procedure

A mixture of (R)-5-(1-methanesulfonyl-1,2,3,6-tetrahydro-pyridin-4-yl)-2-piperidin-4-yl-2,3-dihydro-furo[2,3-c]pyridine (Intermediate 39, the configuration of the stereocenter is arbitrarily assigned; 110 mg}, 2-chloro-5-trifluoromethyl-pyrimidine (76 mg), K2CO3 (100 mg), and dimethyl sulfoxide (1.5 mL) is stirred at 110° C. for 3 h. After cooling to room temperature, water is added and the resulting mixture is extracted with ethyl acetate. The combined extracts are washed with brine, dried (Na2SO4), and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 30:70→10:90) to give the title compound. LC (method 5): tR=1.32 min; Mass spectrum (ESI+): m/z=510 [M+H]+.
