A suspension of N-(1-methyl-1H-pyrazol-3-yl)-3,5-bis[(phenylmethyl)oxy]benzamide (1.0 g, 2.42 mmol) was dissolved in ethanol (12 mL) and ammonium formate (229 mg, 3.63 mmol) was added in one portion. The reaction was blanketed with argon and 10% Palladium on activated carbon (10 mg) was added. This mixture was heated to 140° C. for 5 minutes in a Smith Creator microwave. The catalyst was filtered off and the volatiles removed in vacuo, the residue was chromatographed on silica, eluting with a gradient of 30-100% ethyl acetate in iso-hexane, to give the title compound as a white solid (378 mg). 1H NMR δ (d6-DMSO): 3.78 (3H, s), 5.13 (2H, s), 6.55-6.57 (2H, m), 6.99 (1H, s), 7.17 (1H, s), 7.34-7.48 (5H, m), 7.60 (1H, d), 9.74 (1H, s), 10.70 (1H, s); m/z 324 (M+H)+.
