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
A mixture of 5-methylbenzo[d]isoxazol-3-amine (1.48 g, 10 mmol, 1.0 eq.), B0C2O (6.54 g, 30 mmol, 3.0 eq.), DMAP (122 mg, 1.0 mmol, 0.1 eq.), TEA (4.2 mL, 30 mmol, 3.0eq.) in DCM (30 mL) was refluxed for 18 h. The mixture was washed with water (30 mL X 2), dried over anhydrous Na2SC>4 and concentrated. The residue was purified via flash chromatography (PE/EA/DCM = 1/20/1-1/7/1, v/v/v) to afford tert-butyl [(tert- butoxy)-N-(5-methylbenz (3.2 g, 92%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 89976-56-7, We look forward to the emergence of more reaction modes in the future.
