실험 절차
tert-Butyl 4-[3-(pyridin-3-ylmethyl)-1,2,4-oxadiazol-5-yl]piperidine-1-carboxylate was treated with 10 mL TFA/DCM (1:1) for 30 min at ambient temperature. The reaction mixture was concentrated to give the di-TFA salt of 3-[(5-piperidin-4-yl-1,2,4-oxadiazol-3-yl)methyl]pyridine as an amber oil (4.0 g, 8.47 mmol, 85%, 3 steps). 1H NMR (300 MHz, DMSO-d6) δ 8.78 (s, 1H), 8.70 (d, 1H, J=5.0 Hz), 8.51 (br.s, 1H), 8.18 (d, 1H, J=7.9 Hz), 7.75 (m, 1H), 4.30 (s, 2H), 3.44-3.30 (m, 3H), 3.09-3.00 (m, 2H), 2.20-2.16 (m, 2H), 1.93-1.80 (m, 2H).
