Procedure

Using the procedure described in Example 306A, to a solution of 3-tert-butyl-1-(5-fluoropyridin-3-yl)-1H-pyrazol-5-amine (423 mg, 2.1 mmol), described in the previous step, and potassium carbonate (290 mg, 2.1 mmol) in anhydrous DCM (3.4 ml) was added dropwise phenyl chloroformate (0.61 ml, 4.8 mmol) as a solution in DCM (2 ml) to afford phenyl 3-tert-butyl-1-(5-fluoropyridin-3-yl)-1H-pyrazol-5-ylcarbamate (411 mg, 72%). 1H NMR (300 MHz, CDCl3) δ 1.28 (s, 9H), 6.47 (s, 1H), 6.95-7.41 (m, 7H), 7.72-7.82 (m, 1H), 8.40 (d, J=8 Hz, 1H); LC-MS (ESI) m/z 355 (M+H)+.
