Procedure

Using the procedure in Example 118A, 3-tert-butyl-1-(2-fluorophenyl)-1H-pyrazol-5-amine (1.23 g, 5.27 mmol) and phenyl chloroformate (2.0 mL, 16.0 mmol) were reacted to give phenyl 3-tert-butyl-1-(2-fluorophenyl)-1H-pyrazol-5-ylcarbamate (1.21 g, 3.42 mmol, 59%). 1H NMR (300 MHz, DMSO-d6) δ 10.13 (s, 1H), 7.55-7.35 (m, 6H), 7.23 (t, 1H), 7.08 (br s, 2H), 6.34 (s, 1H), 1.29 (s, 9H); LC-MS (ESI) m/z 354 (M+H)+.
