実験手順

A solution of 4-bromo-2-ethylaniline (200 mg) in dichloromethane (10 mL) was treated with 1-fluoro-2-isocyanato-4-methylbenzene (151 mg), stirred at room temperature overnight, diluted with hexanes, and filtered. The filter cake provided 227 mg of the desired product. MS (ESI(+)) m/e 351,353 (M+H)+.
