Vorschrift

3-Chlorobenzoylchloride (110.0 g, 57.1 mmol) was dissolved in dichloromethane (200 mL), and the solution was added with cumylamine (9.04 mL, 62.9 mmol), triethylamine (12.0 mL, 85.7 mmol) and DMAP (698 mg, 5.71 mmol), followed by stirring at room temperature for 3 hours. The reaction mixture was added with water, extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by slurry using diisopropyl ether to obtain 3-chloro-N-(1-methyl-1-phenylethyl)benzamide (15.0 g, yield 96%).
