Procedure

A suspension of 3-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)-5-[(phenylmethyl)oxy]benzamide (450 mg, 1.39 mmol), (3R)-tetrahydrofuran-3-yl 4-methylbenzenesulfonate (507 mg, 2.09 mmol) and potassium carbonate (481 mg, 3.48 mmol) in acetonitrile (5 mL) was stirred in a Smith Creator microwave at 160° C. for 3 hours. The solvent was removed in vacuo and ethyl acetate added. The organics were washed with water (40 mL), brine (40 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give a yellow foam which was chromatographed on silica, eluting with a gradient of 0-100% ethyl acetate in iso-hexane, to give the title compound as a white foam (452 mg). 1H NMR δ (CDCl3): 2.09-2.14 (1H, m), 2.14-2.24 (1H, m), 3.68 (3H, s), 3.86-3.91 (1H, m), 3.94-3.98 (3H, m), 4.89 (1H, s), 5.03 (2H, s), 6.64 (1H, t), 6.85 (1H, s), 6.96 (1H, d), 7.07 (1H, t), 7.27 (1H, m), 7.33-7.41 (5H, m), 9.31 (1H, s); m/z 394 (M+H)+.
