Reaction Steps

Reaction of phenoxazine with 5-methyl-2-pyrrolidinone according to the procedure of Example 1 affords the free base 10-(5-METHYL-1-PYRROLIN-2YL)PHENOXAZINE, m.p. 135°-137° C., from n-heptane. Conversion of the free base to the hydrochloride salt provides 10-(5-METHYL-1-PYRROLIN-2YL)PHENOXAZINE HYDROCHLORIDE, m.p. 229.5°-236.0° C. (dec.) (corr.), in a 57% overall yield.
