Reaction Steps

A toluene [350 milliliters (mL)] solution of 3-aminobenzotrifluoride [35.5 grams (g) 0.22 mol] and pyridine (19.1 grams, 0.24 mol) was cooled in an ice bath. 2-Chloro-2-phenylacetyl chloride (45.8 grams, 0.24 mol) was added dropwise. The mixture was allowed to warm to room temperature and stirred overnight. The reaction mixture was diluted with ethyl acetate (100 mL) and washed with water (2 ×200 mL) and dried with magnesium sulfate. The solvent was removed in a rotary evaporator to provide the desired N-(3-trifluoromethylphenyl)-2-chloro-2-phenylacetamide (61.6 grams, 89% yield) whose structure was confirmed by nuclear magnetic resonance, infra-red spectroscopy, and mass spectroscopy analysis.
