Triethylamine → 2-{[4-Cyano-2-methyl-3-(trifluoromethyl)phenyl]amino}-2-oxoethyl acetate

Participants

Reaction Steps

To a solution of 4-amino-3-methyl-2-(trifluoromethyl)benzonitrile (commercially available, for example from Sunshine Chemlab, Downington, Pa., USA, 500 mg, 2.50 mmol) and triethylamine (0.383 mL, 2.75 mmol) in dichloromethane (10 mL) was added 2-chloro-2-oxoethyl acetate (0.269 mL, 2.50 mmol) dropwise. The reaction mixture was stirred at room temperature for 3 hours. The reaction mixture was diluted with DCM (100 ml) and water (50 ml) and aqueous was extracted with DCM (100 ml). The organics were combined, passed through a phase separator and concentrated to afford 710 mg of the title compound as a pale yellow powder.
