In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 89976-56-7,5-Methylbenzo[d]isoxazol-3-amine, as follows.89976-56-7

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
