tert-Butyl [(1R,3S)-3-(2-methoxyethyl)-3-(4-[4-(trifluoromethyl)pyridin-2-yl]piperazin-1-ylcarbonyl)cyclopentyl]carbamate (252 mg, 0.503 mmol) was dissolved in a 2 M solution of hydrogen chloride in ether (8 mL) and stirred at room temperature for 2 h. The reaction solution was concentrated to give the desird product as a yellow powder (0.36 g, 96%). MS calculated for C19H27F3N4O2 (M+H) 401.3; found 401.3.
