With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.864274-04-4,2-Methylbenzo[d]oxazole-6-carbaldehyde,as a common compound, the synthetic route is as follows.,864274-04-4
Example 72; 5-(2-Methyl-benzooxazol-6-ylmethylene)-2-(2-piperidin-l-yl-ethylimino)-thiazolidi n-4-one; a) 5- (2-Methyl-benzooxazol-6-ylmethylene)-2-thioxo-thiazolidin-4-one; To the solution of rhodanine (1.21 g, 10 mmol) in ethanol (50 mL) was added 2-methyl-benzooxazole-6-carbaldehyde (1.61 mg, 10 mmol, 1 eq) followed by pyridine (1 mL). The reaction mixture was refluxed for 24 hours cooled to the room temperature. Solid was filtered to give 1.3 g (47 percent yield) of pure 5-(2-methyl-benzooxazol-6-ylmethylene)-2-thioXo-thiazolidin-4-one. lH-NMR (DMSO): No. 2.67 (s, 3H), 2.85 (s, 3H), 7.66 (dd, 1H, J=8.3 Hz, J’=1. 7 Hz), 7.82 (d, 1H, J=8.3 Hz), 8.00 (s, 1H), 8.02 (d, 1H, J=1.7 Hz). LC MS (m/e) = 277.0 (MH+). Rt = 2.02 min.
The synthetic route of 864274-04-4 has been constantly updated, and we look forward to future research findings.
