Reaction Steps

A mixture of 4-(2-methyl-1H-imidazol-1-yl)-3-(trifluoromethyl)-benzonitrile (1.01 g, 4 mmol), 6 mL of acetic acid and 3 mL of 12M hydrochloric acid (37%) is shaken for 16 hours at 95° C. After cooling, the reaction mixture is evaporated to dryness under reduced pressure. The resulting residue is evaporated twice with toluene, dissolved in water and the pH is adjusted to ˜5-6 by dropwise addition of 1M sodium hydroxide solution. The aqueous phase is extracted twice with n-butanol and the organic phase evaporated to yield the title compound as a beige solid.
