実験手順

A mixture of 2-fluoro-4-[5-(methylsulfonyl)-2-pyridinyl]phenol (0.114 g, 0.43 mmol), 1-methylethyl 4-{[(methylsulfonyl)oxy]methyl}-1-piperidinecarboxylate (0.18 g, 0.55 mmol) and K2CO3 (0.12 g, 0.85 mmol) in DMF (5 mL) was stirred at ambient temperature for 30 min, then heated at 70° C. overnight. Cooled to ambient temperature, the mixture was poured into water (30 mL), and the precipitate was collected, washed with water and air dried. The solid was further triturated with hot MeOH to give 0.125 g (65%) of the title compound as a white solid. 1H NMR (400 MHz, CDCl3): δ 9.14 (d, 1H, J=1.7 Hz), 8.23 (dd, 1H, Ja=8.4 Hz, Jb=2.0 Hz), 7.90-7.75 (m, 3H), 7.05 (t, 1H, J=8.4 Hz), 4.92 (septet, 1H, J=6.2 Hz), 4.30-4.10 (m, 2H), 3.94 (d, 2H, J=6.6 Hz), 3.13 (s, 3H), 2.85-2.70 (m, 2H), 2.15-2.00 (m, 1H), 1.95-1.80 (m, 2H), 1.40-1.25 (m, 2H), 1.24 (d, 6H, J=6.3 Hz); LRMS (ESI), m/z 451 (M+H).
