実験手順

A mixture of 3-hydroxy-5-{[(1S)-1-methylpropyl]oxy}-N-(1-methyl-1H-pyrazol-3-yl)benzamide (0.116 g, 0.4 mmol), 2-(azetidin-1-ylcarbonyl)-5-bromopyridine (116 mg, 0.48 mmol), cesium carbonate (392 mg, 1.2 mmol) and bromotris(triphenylphosphine)copper(I) (38 mg, 0.04 mmol) in DMA (5 mL) was stirred in the microwave reactor at 160° C. for 4 hours. The product was dissolved in ethyl acetate (20 mL) and water (15 mL) and the layers separated. The organic layer was washed with brine (50 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give a brown oil which was chromatographed on silica, eluting with a gradient of 0-5% methanol in ethyl acetate, and then re-columned on silica, eluting with a gradient of 0-5% methanol in DCM, to give the desired compound as a white foam which crystallised on standing. The material was triturated with 50% ethyl acetate in hexane to give the required product as a white solid (95 mg). 1H NMR δ (CDCl3): 0.90 (t, 3H), 1.23 (d, 3H), 1.51-1.72 (m, 2H), 2.28 (quin, 2H), 3.73 (s, 3H), 4.18 (t, 2H), 4.28 (q, 1H), 4.64 (t, 2H), 6.67 (t, 1H), 6.72 (d, 1H), 6.99 (s, 1H), 7.15 (s, 1H), 7.22 (d, 1H), 7.31 (d, 1H), 8.04 (d, 1H), 8.26 (s, 1H), 8.41 (s, 1H); m/z 450 (M+H)+
