Participants

Reaction Steps

To a stirred solution of 3-(5-bromo-4-chloro-2-methoxyphenyl)propanoic acid (350 mg, 1.2 mmol) in DMF (30 mL) at RT, tert-butyl 3-(piperazin-1-yl)azetidine-1-carboxylate (317 mg, 1.3 mmol), BOP (731 mg, 1.4 mmol) and DIEA (461 mg, 3.6 mmol) were added and the mixture was stirred at RT for 1 h. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine and dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (dichloromethane/methanol=50:1) to afford the desired product (285 mg, 46% yield).
