Reaction Steps

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide 4-hydrochloride (8.88 g), 4-dimethylaminopyridine (5.67 g) and a 2M solution of methylamine in tetrahydrofuran (23 ml) were added to a solution of 4-bromophenylacetic acid (5.0 g) in dichloromethane (100 ml). The mixture was stirred overnight at room temperature. The reaction mixture was washed with 2M hydrochloric acid (3×100 ml), the organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated. The sub-title compound was obtained as a solid (4.74 g) after recrystallisation from 1% hexane in ethyl acetate.
