Reaction Steps

To a solution of N-(1-(5-fluoropyridin-3-yl)-3-formyl-1H-pyrazol-4-yl)isobutyramide (0.315 g, 1.140 mmol) in methanol (5.70 ml) at 0° C. was added sodium borohydride (0.086 g, 2.280 mmol). The reaction was stirred at 0° C. for 2 hours, and room temperature for 20 hours. 0.5 M HCl was added, the reaction was neutralized with saturated aqueous sodium bicarbonate, and the mixture was extracted with dichloromethane. The organic phases were concentrated and chromatographed (0-100% ethyl acetate/hexanes) to give N-(1-(5-fluoropyridin-3-yl)-3-(hydroxymethyl)-1H-pyrazol-4-yl)isobutyramide (180 mg, 0.647 mmol, 56.7%) as a white solid and N-(1-(5-fluoropyridin-3-yl)-1H-pyrazol-4-yl)isobutyramide (9 mg, 0.036 mmol, 3.18%) as a white solid.
