Reaction Steps

A 4 N solution (15 ml) of hydrogen chloride in ethyl acetate was added to a solution of tert-butyl 4-[4-(2,3-dichlorophenyl)-1,3-thiazol-2-yl]piperazine-1-carboxylate (370 mg, 0.893 mmol) in ethyl acetate (15 ml), the mixture was stirred at room temperature for 14 hours, and the solvent was distilled off under reduced pressure. The residue was dissolved in water, neutralized with a 1 N sodium hydroxide aqueous solution, and extracted with chloroform. The extract was washed with water, and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to give 231 mg (82.1%) of the desired product as a solid.
