Reaction Conditions

Reaction Steps

A mixture of 3-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)-5-[(3R)-tetrahydrofuran-3-yloxy]benzamide (150 mg, 0.49 mmol), 2-(azetidin-1-ylcarbonyl)-5-bromopyridine (120 mg, 0.49 mmol), bromotris(triphenylphosphine)copper (92 mg, 0.10 mmol) and caesium carbonate (484 mg, 1.48 mmol) in acetonitrile (7 mL) was stirred in a microwave reactor at 160° C. for 6 hours. The solid was filtered off, the solvent was removed in vacuo and ethyl acetate (50 mL) added to the residue. The organic phase was washed with water (10 mL), brine (20 mL), dried (MgSO4), filtered and the solvent removed in vacuo. The residue was chromatographed on silica, eluting with a gradient of 0-10% methanol in DCM, to give the title compound as a white solid (86 mg). 1H NMR δ (CDCl3): 2.10-2.17 (m, 1H), 2.19-2.25 (m, 1H), 2.32-2.38 (m, 2H), 3.76 (s, 3H), 3.87-3.92 (m, 1H), 3.95-4.01 (m, 3H), 4.24 (t, 2H), 4.71 (t, 2H), 4.97 (t, 1H), 6.73 (t, 1H), 6.81 (s, 1H), 7.11 (s, 1H), 7.24 (s, 1H), 7.27-7.30 (m, 1H), 7.36-7.39 (m, 1H), 8.12 (d, 1H), 8.31 (d, 1H), 8.72 (s, 1H); m/z 464 (M+H)+.
