実験手順

To a solution of ethyl 1-((6-((4-tert-butylcyclohexylidene)methyl)naphthalen-2-yl)methyl)piperidine-4-carboxylate (50 mg, 0.11 mmol) in MeOH (3 mL) was added NaOH (22 mg, 0.55 mmol, 5.0 eq) and H2O (0.5 mL). The reaction mixture was stirred at 80° C. for 4 h. The pH of the solution was adjusted to 6 with 3 N HCl. The mixture was filtered and the yellow solid was the desired product 1-((6-((4-tert-butylcyclohexylidene)methyl)naphthalen-2-yl)methyl)piperidine-4-carboxylic acid (35 mg, yield: 81%). ESI-MS (M+1)+: 420.1. 1HNMR (400 MHz, CD3OD) δ: 7.86 (s, 1H), 7.83˜7.80 (m, 1H), 7.77-7.74 (m, 1H), 7.60 (br, 1H), 7.43 (d, J=8.4 Hz, 1H), 7.35˜7.32 (m, 1H), 6.30 (s, 1H), 4.29 (s, 2H), 3.33 (br, 2H), 2.97-2.94 (m, 3H), 2.42-2.38 (m, 2H), 2.20-2.03 (m, 1H), 2.03-2.00 (m, 2H), 1.89-1.80 (m, 5H), 1.22-1.12 (m, 3H), 0.80 (s, 9H). HPLC: 100%.
