Procedure

Following the procedure in Example 118A, 3-tert-butyl-1-(pyridin-4-yl)-1H-pyrazol-5-amine (250 mg, 1.16 mmol) and phenyl chloroformate (0.60 mL, 4.65 mmol) were reacted to give phenyl 3-tert-butyl-1-(pyridin-4-yl)-1H-pyrazol-5-ylcarbamate (90 mg, 0.27 mmol, 23%). 1H NMR (300 MHz, DMSO-d6) δ 10.15 (br s, 1H), 8.72 (d, 2H), 7.76 (d, 2H), 7.40-7.05 (m, 5H), 6.45 (s, 1H), 1.29 (s, 9H); LC-MS (ESI) m/z 337 (M+H)+.
