With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1771-18-2,2-Methoxyphenothiazine,as a common compound, the synthetic route is as follows.
EXAMPLE 5 Reaction of 5-methyl-2-pyrrolidinone, 2-methoxyphenothiazine and phosphorus oxychloride in 1,2-dichloroethane according to the procedure of Example 4 affords 2-METHOXY-10-[5-METHYL-1-(5-METHYL-1-PYRROLIN-2-YL)-2-PYRROLIN-2-YL]PHENOTHIAZINE HYDROCHLORIDE (8.6% yield), m.p. 236.5-238.5 C. (corr.), from ethanol-ether.
The synthetic route of 1771-18-2 has been constantly updated, and we look forward to future research findings.
