Reaction Steps
Reaction of 2-methoxyphenoxazine, 5-methyl-2-pyrrolidinone and phosphorus oxychloride according to the procedure of Example 1 provides the free base 2-METHOXY-10-(5-METHYL-1-PYRROLIN-2-YL)PHENOXAZINE as an oil. Conversion of the free base to the hydrochloride salt affords 2-METHOXY-10-(5-METHYL-1-PYRROLIN-2-YL)PHENOXAZINE HYDROCHLORIDE, m.p. 223.5°-224.5° C. (dec.)(corr.), as the hemihydrate by trituration with acetone.
