Procedure

To a solution of ethyl 1-(2-bromoacetyl)cyclopropanecarboxylate (4.7 g, 20 mmol) in THF (60 mL) was added (R)-α-methylbenzylamine (2.9 g, 24 mmol) and Et3N (4.04 g, 40 mmol). After stirring at rt for 3 days, the reaction mixture was concentrated in vacuo, and the residue was extracted with EtOAc (50 mL×2) and washed with water (30 mL). The combined organic phases were dried over anhydrous Na2SO4, filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (EtOAc) to afford the title compound as a yellow solid (3.66 g, 80%).
