Reaction Steps

To a solution of (3R)-3-((S)-1-(3-fluorophenyl)-1-hydroxy-5-methoxypentyl)-N-(3-(1-hydroxycyclohexyl)-2-(N-methyl-N-(2-(trimethylsilyl)ethoxycarbonyl)amino)propyl)piperidine-1-carboxamide (9.7 mg, 0.015 mmol) in anhydrous THF (1 mL) was added Et4NF (3 mg). The solution was stirred at 45° C. for 2 h and evaporated under reduced pressure. The residue was purified by prep HPLC to give (3R)-3-((S)-1-(3-fluorophenyl)-1-hydroxy-5-methoxypentyl)-N-(3-(1-hydroxycyclohexyl)-2-(methylamino)propyl)piperidine-1-carboxamide (4.5 mg, 50%) as its TFA salt. 1H NMR (400 MHz, CD3OD): 7.32 (t, 1H), 7.16 (d, 1H), 7.14 (d, 1H), 6.94 (td, 1H), 4.36 (t, 1H), 3.88 (t, 1H), 3.53 (m, 1H), 3.40 (m, 1H), 3.26 (s, 3H), 2.61 (s, 3H), 2.48 (m, 1H), 2.47 (m, 1H), 1.94 (t, 2H), 1.90 (td, 1H), 1.76 (tt, 1H), 1.69-1.22 (m, 18H), 0.99 (m, 1H); MS m/z 524 (M+H+).
