Reaction Steps
A mixture consisting of 50 mL dioxane, 25 mL water and 18.75 mL 2M aqueous sodium hydroxide solution is added to 3-(4-methyl-1-piperazinyl)-5-(trifluoromethyl)-benzonitrile (2.69 g, 10 mmol) and the reaction mixture shaken for 16 hours at 95° C. After cooling, the mixture is evaporated to dryness under reduced pressure. The resulting residue is treated with water, the pH adjusted to ˜5-6 with 2M hydrochloric acid. The precipitate is filtered off and the filtrate extracted twice with n-butanol. The combined organic extracts are evaporated to yield the title compound as a solid.
