To a solution of (R)-3-((S)-1-(2-(2-ethylphenoxy)phenyl)-1-hydroxy-5-methoxy pentyl)piperidine-1-carbonyl chloride (<0.05 mmol) in CH2Cl2, there was added excess 1,3-diaminopropan-2-ol (˜0.1 mL). The resulting solution was stirred at rt for 1 h, the CH2Cl2 was removed, and the residue was purified by prep HPLC to give (3R)-3-((S)-1-(2-(2-ethylphenoxy)phenyl)-1-hydroxy-5-methoxypentyl)-N-(3-amino-2-hydroxypropyl)piperidine-1-carboxamide (10.0 mg, 39%) as its TFA salt. 1H NMR (400 MHz, CD3OD): 7.64 (d, 1H), 7.32 (d, 1H), 7.04-7.20 (m, 4H), 6.74 (d, 1H), 6.56 (d, 1-H), 4.40 (d, 1H), 3.82 (m, 2H), 3.26 (t, 2H), 3.24 (s, 3H), 2.96 (m, 1H), 2.78 (m, 2H), 2.62 (q, 2H), 2.40 (m, 2H), 1.94 (m, 1H), 1.22-1.64 (m, 7H), 1.08 (t, 3H), 0.98 (m, 1H); MS m/z 514 (M+H+).
