The synthetic route of 3209-70-9 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3209-70-9,Ethyl isoxazole-3-carboxylate,as a common compound, the synthetic route is as follows.,3209-70-9

(i) The preparation of 3-aminomethylisoxazole is described below: Di-isobutylaluminium hydride (1.5M in toluene, 29 ml) was added to a solution of ethyl isoxazole-3-carboxylate (6.1 g; Can. J. Chem., 1970, 48, 475) in toluene (20 ml) which was cooled in an ice-bath. The mixture was stirred at laboratory temperature for 16 hours. The analysis indicated that the reduction was incomplete. A second portion of di-isobutylaluminium hydride (28.8 ml) was added and the mixture was stirred for 16 hours. The bulk of the toluene was evaporated and the mixture was poured into a saturated aqueous ammonium chloride solution. The precipitate was filtered off and dried. There was thus obtained 3-hydroxymethylisoxazole (2.1 g).

The synthetic route of 3209-70-9 has been constantly updated, and we look forward to future research findings.
