A solution of 1 ,2-benzisoxazol-3-amine (1.00 g; CASNo. 36216-80-5) and triethylamine (1.09 mL) in acetonitrile (5 mL) was added dropwise to at 0 0C solution of phenyl chloroformate (0.989 mL) in THF (20 mL). The reaction was stirred at 0 0C for 1 h and then allowed to warm to room temp overnight. The reaction was diluted with ethyl acetate and washed with 1 N HCI and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated to give the crude product as a reddish brown solid. The solid was triturated with refluxing diisopropyl ether, cooled to room temp, and filtered to give the final product as a tan solid (1.22 g, 64%). m/z 255 (MH+).
