Procedure

A mixture of 3-[(2S)-1-(difluoromethoxy)propan-2-yl]oxy-5-hydroxy-N-(1-methylpyrazol-3-yl)benzamide (100 mg, 0.29 mmol), 5-bromo-2-methylsulfonyl-pyridine (CAS no. 98626-95-0) (77 mg, 0.32 mmol), cesium carbonate (191 mg, 0.59 mmol) and bromotris(triphenylphosphine)copper(I) (55 mg, 0.06 mmol) in DMA (5 mL) was stirred in a microwave reactor at 160° C. for 6 hours. Ethyl acetate (50 mL) was added and washed with water (50 mL), brine (50 mL), dried (MgSO4), filtered and reduced in vacuo. The residue was chromatographed on silica, eluting with 10-80% ethyl acetate in isohexane to give the desired compound (31 mg).
