With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1072-67-9,5-Methylisoxazol-3-amine,as a common compound, the synthetic route is as follows.
General procedure: To a suspension of 4-hydroxyquinolin-2(1H)-one (7, 1 mmol, 161 mg) in H2O:EtOH(1:1) (8 mL), DBU (20 mol%) was added. The reaction mixture was heated and stirred at 50 C for 15 min to dissolve the reactant. Then, aryl glyoxal monohydrates(1a-h, 1 mmol), 5-methylisoxazol-3-amine (6, 1 mmol, 98 mg) were added to the reaction mixture, which was stirred at the above-mentioned temperature for appropriate times as shown in Table 2. The progress of reaction was controlled by TLC using MeOH:CHCl3/1:10 as eluent. After completion of the reaction, the precipitate was filtered, washed with water and dried to give the desired products 8a-h in high yield (82-89%)., 1072-67-9
The synthetic route of 1072-67-9 has been constantly updated, and we look forward to future research findings.
