With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3889-13-2,5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one,as a common compound, the synthetic route is as follows.
Step: 23bSynthesis of 5-Amino-3H-benzooxazol-2-Procedure:Pd-c (1 1 lmg) was added to a stirred solution of 5-Nitro-3H-benzooxazol-2-one (1.1 1 lg, 6.168mmol) was dissolved in Methanol (20ml) and THF (10ml). The contents were hydrogenated with stirring for 6 hrs. The reaction was monitored by the TLC (10% CHC13: MeOH). The resulting reaction mixture was filtered through celite, concentrated and washed with hexane. The solid obtained was dried under reduced pressure to afford 930mg (100% yield) of 5-Amino-3H-benzooxazol-2-one., 3889-13-2
The synthetic route of 3889-13-2 has been constantly updated, and we look forward to future research findings.
