3-Chloro-4-morpholinoaniline → N-(3-chloro-4-morpholinophenyl)-3-oxobutanamide

Participants

Reaction Steps

To a solution of 3-chloro-4-morpholinoaniline (2.05 g, 9.64 mmol) in EtOAc (30 mL) was added acetyl ketene (1.62 g, 19.3 mmol) with stirring and the mixture was stirred at 80° C. overnight. The mixture was cooled to rt and concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=3:1) to give the title compound as a pale yellow solid (2.59 g, 91%).
