Reaction Steps
A mixture of 3-({(1S)-2-[(difluoromethyl)oxy]-1-methylethyl}oxy)-5-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)benzamide (220 mg, 0.64 mmol), 2-(azetidin-1-ylcarbonyl)-5-bromopyridine (171 mg, 0.71 mmol), cesium carbonate (419 mg, 1.29 mmol) and bromotris(triphenylphosphine)copper(I) (300 mg, 0.32 mmol) in DMA (5 mL) was stirred in a ‘Biotage initiator Microwave’ at 160° C. for 4 hours. The reaction mixture was added to ethyl acetate (50 mL) and water (50 mL), the organic layer washed with brine (50 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give a brown oil. The residue was chromatographed on silica, eluting with 0-100% ethyl acetate in isohexane, to give the desired compound (102 mg).
