1,2-Dichloroethane → 5-methyl-2-{[(1-{[(1R,2R)-2-phenylcyclopropyl]carbonyl}piperidin-4-yl)methyl]amino}pyrimidine

Participants

Reaction Steps

A solution of 5-methyl-N-(piperidin-4-ylmethyl)pyrimidin-2-amine (5.00 g, 0.024 mol), (1R,2R)-2-phenylcyclopropanecarboxylic acid (T. Riley et al., J. Med. Chem., (1972), 15, 1187) (3.93 g, 0.024 mol), EDC (6.97 g, 0.036 mol) and HOBt (4.91 g, 0.036 mol) in DMF (50 mL) was stirred at RT for 2 h. The reaction mixture was diluted with ethyl acetate (400 mL), washed with aqueous saturated NaHCO3 (100 mL), water (5×100 mL), brine (50 mL), dried over anhydrous sodium sulfate, filtered and concentrated. The residue was chromatographed on silica gel 60 (400 g), eluting with 50–100% ethyl acetate in hexane to give 5-methyl-2-{[(1-{[(1R,2R)-2-phenylcyclopropyl]carbonyl}piperidin-4-yl)methyl]amino}pyrimidine. M.S. (M+1): 351.
