Procedure
A mixture of methyl 4-bromo-2-(bromomethyl)benzoate (Ark Pharm, Cat. No. AK-26333) (0.5 g, 0.002 mol), cyclopropylamine (0.17 mL, 0.0024 mol) and potassium carbonate (0.45 g, 0.0032 mol) in ethanol (5 mL) was stirred at 40° C. for 3 h. The reaction mixture was quenched with water and extracted with ethyl acetate. The organic layers were washed with brine, dried with Na2SO4, filtered, and concentrated under reduced pressure to give a crude product which was directly used in nest step reaction without further purification. LCMS (M+H)+=252.0/254.0.
