実験手順

To a mixture of 5-acetoxy-12H-benzo[a]phenothiazine (3.0 g) and powdered 4 Angstrom molecular sieves (7.5 g) in 1,2-dichloroethane (75 ml) there was added slowly acetyl bromide (1.05 ml). The mixture was stirred at room temperature for 1 hour, then filtered. The filtrate was evaporated down to an oil which was triturated with a mixture of ether and hexane to afford solid title product (3 g), m.p. 141°-142° C.
