To a solution of t-butyl 4-(3-(1-(3,5-dichlorophenyl)ethylamino)-4-(2,2,2-trifluoroacetyl)phenyl)piperazine-1-carboxylate (50.1 mg, 0.09 mmol) in dichloromethane (2.0 mL) was added a saturated solution of HCl in diethyl ether (15 mL). The reaction mixture was stirred for 2 hours. The solvent was removed by rotary evaporation to afford the title compound (42.0 mg, 95% yield). 1H NMR (400 MHz, CD3OD): δ 7.67 (d, 1H), 7.37 (s, 2H), 7.35 (s, 1H), 6.41 (d, 1H), 5.84 (s, 1H), 4.79 (m, 1H), 3.57 (m, 4H), 3.25 (m, 4H), 1.61 (d, 3H); MS (ESI) m/z: Calculated for C20H21Cl2F3N3O: 446.1; Observed: 446.5 (M++1) [corresponding to the free base].
