Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 5-Methyl-2-pyrrolidone | HCID 66055 | — |
| Reactant | Phenoxazine | HCID 67278 | — |
| Product | 10-(2-Methyl-3,4-dihydro-2H-pyrrol-5-yl)-10H-phenoxazine | HCID 22754255 | — |
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-2-YL)PHENOXAZINE, m.p. 135-137° C., from n-heptane. Conversion of the free base to the hydrochloride salt provides 10-(5-METHYL-1-PYRROLIN-2-YL)PHENOXAZINE HYDROCHLORIDE, m.p. 229.5-236.0° C. (dec.) (corr.) in a 57% overall yield.
