Procedure

To a solution of the product of example 1 (2.4 mmol) in THF (10 ml) was added compound 1-amino-3-(4-fluoro-phenyl)-propan-2-one hydrochloride (1.0 g, 4.9 mmol), EDCI.HCl (560 mg, 2.9 mmol), HOBt (400 mg, 2.9 mmol) and TEA (1 g, 9.9 mmol), successively at room temperature. The mixture was stirred overnight, after which saturated sodium bicarbonate was added and then extracted with ethyl acetate. The extracts were combined, washed with brine, and then dried over sodium sulfate. The product was purified by column chromatography to give the desired product.
