Procedure

To a solution of (3S,5R,6S)-3-allyl-5-(3-chlorophenyl)-6-(4-chlorophenyl)-3-methylpiperidin-2-one (Example 71, Step D) (100 mg, 0.27 mmol) in 1.3 mL of DMSO was added sodium hydride (60% suspension in mineral oil, 13 mg, 0.32 mmol) at room temperature. The reaction mixture was stirred for 5 minutes, and was treated with 1-(pyrimidin-4-yloxy)-1H-benzo[d][1,2,3]triazole (Example 110, Step A) (170 mg, 0.80 mmol). The reaction mixture was stirred at 110° C. for 13 hours. The reaction mixture was cooled to room temperature, quenched with water and extracted (2×EtOAc). The combined organic layers were washed with sat. aq. NaCl solution, dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. Purification of the residue by flash chromatography (0 to 45% EtOAc/hexanes) provided the title compound as a colorless solid.
