Procedure

To a solution of 2.1 g (5.44 mmol) of (1S,2R)-2-(3-chlorophenyl)-1-(4-chlorophenyl)-N-(dicyclopropylmethyl)but-3-en-1-amine (Example 115, Step F) and triethylamine (1.89 mL, 13.59 mmol) in THF (30.0 mL) was added acryloyl chloride (0.66 mL, 8.15 mmol) at 0° C. The resulting reaction mixture was stirred at rt for 2 h. When LCMS indicated completion of the reaction, 100 ml of ethyl acetate was added and the combined organics were washed consecutively with water (10 ml), citric acid (10 ml, 1M), NaHCO3 solution (10 ml) and sat. NaCl solution (30 ml), dried over MgSO4, filtered and the filtrate was concentrated. The crude product was purified by flash chromatography on silica gel (eluent: hexane/ethyl acetate, 90/10 to 20/80) to give the title compound.
