Potassium Hydroxide → HCID 24990093、化合物

N-[3-(1-{[4-(4-methoxyphenylthio)phenyl]methyl}(4-piperidyl))-4-methylphenyl] (phenylmethoxy)carboxamide (486 mg, 0.881 mmol) was dissolved in methanol (10.0 mL) and a KOH solution (40%, 1.20 mL) was added. The reaction mixture was heated at 100° C. for 10 h. After cooling to room temperature, the reaction mixture was poured into a separatory funnel. The phases were separated and the aqueous phase was extracted with CH2Cl2 (2×20 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. Purification by flash column chromatography (eluent: Hexane:EtOAc (1:1 then 1:4)) gave 3-(1-{[4-(4-methoxyphenylthio)phenyl]methyl}(4-piperidyl))-4-methylphenylamine (362 mg, 98.2% yield). 1H NMR (400 MHz; CDCl3) δ 7.43-7.35 (m, 4H), 7.24-7.11 (m, 3H), 6.93-6.85 (m, 2H), 6.63-6.58 (m, 1H), 6.48-6.42 (m, 1H), 3.82 (s, 3H), 3.48 (s, 2H), 3.03-2.91 (m, 2H), 2.68-2.54 (m, 1H), 2.20 (s, 3H), 2.13-1.98 (m, 2H), 1.79-1.64 (m, 4H). ESMS m/e: 419.2 (M+H)+.
