Reaction Steps

To a suspension of 2-[5-hydroxy-3-(1-phenylethyl)pyrazol-1-yl]pyridine-4-carbonitrile (150 mg, 0.5 mmol), NH4Cl (278 mg, 5.2 mmol) in DMF (5 mL) was added NaN3 (338 mg, 5.2 mmol) at r.t. The reaction mixture was stirred at 110° C. for 2 h in a microwave oven. The reaction mixture was then filtered and purified by pre-HPLC to give the title compound (100 mg, 58%) as a brown solid. 1H NMR (400 MHz, CD3OD): δ 1.64 (3H, d, J=7.2 Hz), 4.07-4.12 (1H, m), 7.17-7.19 (1H, m), 7.20-7.35 (4H, m), 7.83 (1H, dd, J=1.2, 5.2 Hz), 8.43 (1H, d, J=5.2 Hz), 8.74 (1H, s). [M+H] Calc'd for C17H15N7O, 334. Found, 334.
