Procedure

Using the procedure described in Example 306A, to a solution of 3-isopropyl-1-phenyl-1H-pyrazol-5-amine (423 mg, 2.1 mmol) and potassium carbonate (378 mg, 2.7 mmol) in anhydrous DCM (8 ml) was added dropwise phenyl chloroformate (0.39 ml, 3.1 mmol) as a solution in DCM (2 ml) to afford phenyl 3-isopropyl-1-phenyl-1H-pyrazol-5-ylcarbamate (229 mg, 54%). 1H NMR (300 MHz, CDCl3) δ 1.27 (d, J=6 Hz, 6H), 3.01 (m, 1H), 6.46 (s, 1H), 7.14-7.36 (m, 2H), 7.38-7.57 (m, 8H); LC-MS (ESI) m/z 322 (M+H)+.
