Reaction Steps
To a suspension of 4-bromo-3-methylbenzoic acid (0.500 g, 2.325 mmol) in dichloromethane (10 ml) and DMF (1 drop) was added oxalyl dichloride (0.2231 ml, 2.558 mmol), and the reaction was stirred for 30 minutes. N-ethyl-N-isopropylpropan-2-amine (0.8934 ml, 5.115 mmol) and 2-(4-chlorophenyl)ethanamine (0.3557 ml, 2.558 mmol) were added, and the reaction was stirred for 1 hour at ambient temperature. The reaction was diluted with EtOAc and washed with 1M hydrochloric acid, saturated sodium bicarbonate, and saturated sodium chloride. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The crude material was purified by recrystallization from EtOAc and hexanes to yield 400 mg of the title compound (48.78% yield).
