実験手順

Following the procedure in Example 118A, 3-tert-butyl-1-(pyridin-3-yl)-1H-pyrazol-5-amine (665 mg, 3.08 mmol) and phenyl chloroformate (705 mg, 4.5 mmol) were reacted to give phenyl 3-tert-butyl-1-(pyridin-3-yl)-1H-pyrazol-5-ylcarbamate (984 mg, 2.93 mmol, 95%). 1H NMR (300 MHz, DMSO-d6) δ 7.42-7.39 (m, 3H), 7.30-7.26 (m, 5H), 6.85 (t, 1H), 6.82 (d, 2H), 1.21 (s, 9H); LC-MS (ESI) m/z 337 (M+H)+.
