The crude 5-methyl-benzo[d]isoxazol-3-ylamine was dissolved in 60 mL CH2Cl2. To this solution was added di-tert-butyl-dicarbonate (14.6 g, 66.8 mmol) and a catalytic amount of DMAP. The reaction mixture was stirred at RT overnight. The mixture was concentrated in vacuo to about 30 mL volume, treated with hexanes and filtered to yield 4.8 g of N,N-di-Boc-5-methyl-benzo[d]isoxazol-3-ylamine as a solid., 89976-56-7

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.
