Reaction Steps
The TFA salt of 4-[3-(4-methoxybenzyl)-1,2,4-oxadiazol-5-yl]piperidine (29 mg, 0.076 mmol) was combined with (1-benzoyl-4-phenylpiperidin-4-yl)acetaldehyde (21 mg, 0.069 mmol) in 2 mL DCM and treated with NaBH(OAc)3 (43 mg, 0.203 mmol) at ambient temperature with agitation for 18 h. 1 mL of saturated aqueous NaHCO3 was added and agitated 1 h. The organic phase was separated and concentrated. The crude product was purified by HPLC to give 1-benzoyl-4-(2-{4-[3-(4-methoxybenzyl)-1,2,4-oxadiazol-5-yl]piperidin-1-yl}ethyl)-4-phenylpiperidine (16.1 mg, 0.026 mmol, 38%) as the formate salt. 1H NMR (300 MHz, CD3OD) δ 7.49-7.37 (m, 9H), 7.28 (m, 1H), 7.20 (d, 2H, J=8.8 Hz), 6.86 (d, 2H, J=8.8 Hz), 4.19 (m, 1H), 3.96 (s, 2H), 3.76 (s, 3H), 3.59 (m, 1H), 3.37-3.20 (m, 3H), 3.12-2.95 (m, 3H), 2.45-1.73 (m, 13H).
