To a solution of 5-methyl-benzo[d]isoxazol-3-ylamine (4.6 g) in anhydrous DCM (50 mL) was slowly added a solution of (Boc)2O in anhydrous DCM (50 mL) and 50 mg of DMAP. After refluxing overnight, TLC showed complete reaction. LCMS/ELSD showed formation of the desired product (M+H: 349.2). The reaction was quenched with aqueous sodium carbonate (1 M, 50 mL) and stirred for 1 hr at room temperature. The organic layer was dried over anhydrous sodium sulfate. After rotary evaporation of most solvent, the concentrated solution was loaded onto a 50 g ISOLUTE silica cartridge and eluted with EtOAc/Hexane (from 1:10 to 1:2). Rotary evaporation of solvent provided a light yellow solid. Trituration with EtOAc/Hexane (1:9) provided a white solid (4.56 g). 1H-NMR (300 MHz, CDCl3) delta 7.47 (d, 1H), 7.40 (d, 1H), 7.37 (s, 1H), 2.48 (s, 3H), 1.41 (s, 18H). LC/MS (ESI): M+H+ 349.2.
