Reaction Steps
Reaction of 2-(trifluoromethyl)phenoxazine, 5-methyl-2-pyrrolidinone and phosphorus oxychloride according to the procedure of Example 1 provides the free base 10-(5-METHYL-1-PYRROLIN-2-YL)-2-(TRIFLUOROMETHYL)PHENOXAZINE as a distillable oil, b.p. 145°-152°C. at 0.03 mm Hg. Conversion of the free base to the hydrochloride salt affords 10-(5-METHYL-1-PYRROLIN-2-YL)-2-(TRIFLUOROMETHYL)PHENOXAZINE HYDROCHLORIDE, m.p. 192.5°-195.5°C. (dec.)(corr.)., in a 45% overall yield.
