Procedure

The title compound was prepared from 3-tert-butyl-1-(4-methoxyphenyl)-1H-pyrazol-5-amine (1.24 g, 5.06 mmol) and phenyl chloroformate (1.90 mL, 15.0 mmol) using the procedure in Example 118A to give phenyl 3-tert-butyl-1-(4-methoxyphenyl)-1H-pyrazol-5-ylcarbamate (1.24 g, 3.40 mmol, 67%). 1H NMR (300 MHz, DMSO-d6) δ 9.96 (br s, 1H), 7.44-7.06 (m, 9H), 6.31 (s, 1H), 3.81 (s, 3H), 1.27 (s, 9H); LC-MS (ESI) m/z 366 (M+H)+.
