Definition

ChEBI: Fenoverine is a member of phenothiazines.

Manufacturing Process

To a hot solution 199.3 g (0.1 mol) of phenothiazine in 2 L of dry benzene was added a little quantity of bromine and then were added dropwise 136 g (0.1 mol) of chloroacetyle chloride. Then a mixture was refluxed for 5 hours. After cooling the mixture was concentrated in vacuo. Product was dissolved at reflux in ethanol absolute and filtered. At room temperature was crystallized chloracetyl-10-phenothiazine with 123°C; yield 242 g.
A mixture of 13.8 g (0.05 mol) of chloracetyl-10-phenothiazine, 11.8 g (0.05 mol) of piperonyl-1-piperazine and 3.9 g (0.05 mol) of pyridine in 200 ml of dry toluene was refluxed for 3 hours. Then the solution was cooled and filtered. The filtrate was concentrated. The crystals of 10-((4-piperonyl-1- piperazinyl)acetyl)phenothiazine was recrystallized from isopropylic ether; M.P. 141-142°C; yield 67%.
