Participants

Reaction Steps

To a solution of (S)-2-(5-bromo-4-chloro-2-methoxyphenylamino)propanoic acid (1.6 g, 5.21 mmol), tert-butyl 3-(piperazin-1-yl)azetidine-1-carboxylate (1.88 g, 7.82 mmol), EDCI.HCl (2.0 g, 10.42 mmol), HOBt (1.41 g, 10.42 mmol) in DMF (20 mL) at 0° C., Et3N (1.58 g, 15.63 mmol) was added. The resulting mixture was stirred at RT for 16 h and then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (methanol/dichloroethane=1:50) to afford the desired product (2.1 g, 76% yield). ESI-MS m/z: 531.3[M+H]+.
