Procedure

A solution of 5-fluoro-N-(piperidin-4-ylmethyl)pyrimidin-2-amine (1.00 g, 4.76 mmol), (1R,2R)-2-phenylcyclopropanecarboxylic acid (T. Riley et al., J. Med. Chem., 15, 1187, 1972) (0.77 g, 4.76 mmol), EDC (1.37 g, 7.13 mmol) and HOBt (0.96 g, 7.13 mmol) in DMF (10 mL) was stirred at rt for 2 h. The reaction mixture was diluted with ethyl acetate (200 mL), washed with aqueous saturated NaHCO3 (50 mL), water (5×50 mL), brine (20 mL), dried over Na2SO4, filtered and concentrated. The residue was chromatographed on silica gel 60 (90 g), eluting with 10:1–15:89–75 CH2Cl2:2-propanol:hexane to give the title compound. M.S. (M+1): 355.
