Reaction Steps

tert-Butyl [(1R,3S)-3- [(3R)-tetrahydrofuran-3-yl]-3-(4- [4-(trifluoromethyl)pyridin-2-yl]piperazin-1-ylcarbonyl)cyclopentyl]carbamate (260 mg, 0.51 mmol) was dissolved in a 2 M solution of hydrogen chloride in ether (8 mL). After being stirred at room temperature overnight, the reaction mixture was concentrated under vacuum to provide the desired product (290 mg) as a light yellow solid. MS calculated for C20H27F3N4O2: (M+H) 413.2; found 413.0.
