Reaction Steps
To 0.58 mmol rac-3-methyl-4-(4-trifluoromethyl-phenyl)-piperazine-1-carboxylic acid tert-butyl ester in 3 ml dioxane was added 8.7 mmol HCl (as a 4 M solution in dioxane), and the mixture was heated at 90° C. for 3 h. The mixture was then cooled 0° C. and diluted with 10 ml ether. The ensuing white crystals were collected by filtration, washing with ether, and dried in vacuo to afford the title compound.
