Procedure

N-(1-Methyl-1H-pyrazol-3-yl)-3-[(phenylmethyl)oxy]-5-[(3S)-tetrahydrofuran-3-yloxy]benzamide (453 mg, 1.15 mmol) was dissolved in ethanol (5 mL) and ammonium formate (182 mg, 2.88 mmol) was added in one portion. The reaction was blanketed with argon and 10% palladium on activated carbon (30 mg) was added. This mixture was heated to 140° C. for 10 minutes in a Smith Creator microwave. The catalyst was filtered off and the volatiles removed in vacuo to give the title product as a white solid (339 mg).
