With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.354795-62-3,3-Methylisoxazol-4-amine,as a common compound, the synthetic route is as follows.
A mixture of 2-[(phenylmethyl)oxy]-5-(4-pyridinyl)benzoic acid (may be prepared as described in Description 79; 0.12 g, 0.36 mmol), EDC (0.14 g, 0.72 mmol) and HOBT (0.11 g, 0.72 mmol) in Nu,Nu-dimethylformamide (2 ml) was stirred in air at room temperature for 1 h, then 3-methyl-4-isoxazolamine (may be prepared as described in Description 91; 100 mg, 1.02 mmol) was added in one charge. The reaction mixture was stirred at 25 C overnight. The reaction mixture was diluted with water (25 ml). The solid was filtered, washed with water (30 ml) and methanol (5 ml x 2), and dried in vacuo to yield the title compound as a grey solid. 72 mg.1HNMR (400 MHz, DMSO- /6): 9.97 (s, 1 H), 9.19 (s, 1 H), 8.63 (d, 2H, J=6.0), 8.18 (d, 1 H, J=2.4), 8.04 (dd, H, J=2.4, J=8.8), 7.75 (d, 2H, J=6.0), 7.56 (d, 2H, J=6.8),7.49-7.38 (m, 4H), 5.34 (s, 2H), 1.95 (s, 3H).MS (electrospray): m/z [M+H]+ = 386.00, 354795-62-3
The synthetic route of 354795-62-3 has been constantly updated, and we look forward to future research findings.
