Reaction Steps

A solution of 1-benzyl-4-hydroxypiperidine (209 mg, 1.1 mmol, 1.1 eq) and 95 w % sodium hydride (1.2 mmol) in 5 ml of dimethylformamide was stirred at a room temperature for 30 min, mixed with 2-chloro-N-(3-chlorophenyl)nicotinamide (1.0 mmol), and stirred for 20 hrs under reflux. The reaction mixture was cooled to a room temperature, and added with 20 ml of pure water to terminate the reaction. After two rounds of extraction with 20 ml of ethylacetate per round, water was removed with a desiccant and the resulting product was concentrated under reduced pressure. Then, the residue obtained by the concentration was subjected to silica gel column chromatography (mobile phase: 30 (v/v) % hexane in EA) to obtain the desired fraction. The desired fraction was dried in a reduced pressure to afford 0.25 g of the title compound (Yield: 33.7%). 1H NMR (CDCl3) δ 8.60 (d, 1H), 8.29 (d, 1H), 7.88 (s, 1H), 7.48 (d, 1H), 7.36-7.27 (m, 6H), 7.17-7.05 (m, 2H), 5.51-5.38 (m, 1H), 3.59 (s, 2H), 2.89-2.80 (m, 2H), 2.42 (t, 2H), 2.29-2.23 (m, 2H), 2.06-1.87 (m, 2H) ppm.
