実験手順

To a suspension of N-(4-(2-methoxyethoxy)-3-(2-methyl-2H-pyrazol-3-yl)phenyl)acetamide (289 mg, 1.0 mmol) in MeOH (3 mL) was added a solution of sodium hydroxide (240 mg, 6.0 mmol) in water (0.4 mL) and the mixture was stirred at 160° C. in a microwave oven. After 30 minutes, the mixture was allowed to cool to room temperature, and the solvent was removed under reduced pressure. The residue was taken up in water, and extracted three times with dichloromethane. The extracts were combined, dried with sodium sulfate, filtered, and evaporated to dryness to afford the title compound (231 mg, 93% yield) as a brown oil which was used without further purification. LCMS m/z (%) 248.1 (M+H, 100%). 1H NMR (400 MHz, DMSO-d6) δ 3.19 (s, 3H) 3.48-3.53 (m, 2H) 3.63 (s, 3H) 3.89-3.96 (m, 2H) 4.81 (s, 2H) 6.16 (d, J=1.77 Hz, 1H) 6.48 (d, J=3.03 Hz, 1H) 6.62 (dd, J=8.72, 2.91 Hz, 1H) 6.86 (d, J=8.84 Hz, 1H) 7.39 (d, J=1.77 Hz, 1H).
