실험 절차

To a solution of 4-(adamantan-1-ylmethoxy)-3-(2-methoxypyridin-3-yl)benzamide (0.39 g, 1.00 mmol) in tetrahydrofuran (30 mL) was added sodium hydride (0.09 g, 2.25 mmol). The reaction mixture was stirred at ambient temperature for 2 h, methanesulfonyl chloride (0.12 mL, 1.54 mmol) was added; stirring was continued for 46 h at ambient temperature and quenched by addition of 5% hydrochloric acid (1.0 mL). Diluted with ethyl acetate (100 mL) and washed with brine; dried over anhydrous sodium sulfate and concentrated in vacuo. Purification of the residue by column chromatography using 10% to 50% gradient ethyl acetate in hexanes to afford the title compound as a colorless solid (0.13 g, 27%): 1H NMR (300 MHz, CDCl3) δ 8.73 (br s, 1H), 8.21-8.17 (m, 1H), 7.88-7.83 (m, 1H), 7.78-7.65 (m, 1H), 7.55-7.50 (m, 1H), 7.00-6.93 (m, 2H), 3.88 (s, 3H), 3.53 (s, 2H), 3.40 (s, 3H), 1.90 (br s, 3H), 1.69-1.31 (m, 12H); MS (ES−) m/z: 469.1 (M−1).
