Reaction Steps
A mixture of tert-butyl 4-(5-(1-(4-(trifluoromethyl)phenyl)piperidin-4-yloxy)-2,3-dihydro-1H-inden-1-ylamino)piperidine-1-carboxylate (0.73 g, 1.3 mmol) and 4N hydrochloric acid in dioxane (4 mL) was stirred at room temperature for 1 h. The reaction mixture was concentrated and washed with diethyl ether (2×5 mL) and then dried under reduced pressure to afford the title compound (as the 3.HCl salt) as a off-white solid (0.57 g, 97%). 1H NMR (CD3OD, 300 MHz) 7.73 (m, 2H), 7.58 (m, 3H), 7.07 (s, 1H), 7.01 (m, 1H), 4.93 (m, 1H), 4.78 (m, 1H), 3.65 (m, 6H), 3.20 (m, 5H), 2.62 (m, 1H), 2.35 (m, 6H), 2.08 (m, 5H) ppm; MS (ES) 460.7 (M+H)
