Procedure

A mixture of 0.200 g (0.663 mmol) of 3-chloro-N-(2,5-dichloro-pyridin-3-yl)-benzamide and 0.190 g (1.33 mmol) of 3-piperdin-4-yl-propan-1-ol in N,N-dimethylformamide (5 mL) is heated to 130° C. and stirred for 2 days. The mixture is cooled to room temperature, diluted with water, and extracted with ethyl acetate. The combined organic phase is washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue is purified by flash silica gel chromatography to provide 0.130 g (47%) of 3-chloro-N-[5′-chloro-4-(3-hydroxy-propyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-3′-yl]-benzamide as a light brown foam.
