Reaction Steps

A solution of tert-butyl ({1-[4-(3-pyrrolidin-1-ylpropoxy)phenyl]cyclohexyl}methyl)-carbamate (600 mg, 1.44 mmol) in Et2O (5 mL) was added dropwise to a stirred solution of LiAlH4 (1.0M solution in Et2O, 4.32 mL, 4.32 mmol) at 0° C. THF (5 mL) was added and the reaction mixture heated at reflux overnight. Reaction mixture was cooled to 0° C. quenched with water (0.5 mL), aqueous NaOH (2.0M, 0.5 mL) and water (0.5 mL). Dichloromethane and ethyl acetate were added and the mixture filtered over a short pad of celite, and concentrated in vacuo. The compound was purified by column chromatography on Biotage® silica gel, eluting with dichloromethane:methanol:ammonia, 96:4:0.4 to 90:10:1 to give the title compound as a clear oil (230 mg, 48%). 1H NMR (400 MHz, CDCl3) δ 7.16 (d, 2H), 6.88 (d, 2H), 4.02 (t, 2H), 2.64 (t, 2H) 2.54 (s, 2H), 2.50-2.58 (m, 4H), 2.26 (s, 3H), 2.14-2.08 (m, 2H), 1.98 (pentet, 2H), 1.84-1.76 (m, 4H), 1.68-1.56 (m, 2H), 1.52-1.32 (m, 6H); HRMS (ESI+) 331.2744 (M+H)+.
