Reaction Steps

A mixture of 3-[(2S)-1-(difluoromethoxy)propan-2-yl]oxy-5-hydroxy-N-(5-methylpyrazin-2-yl)benzamide (190 mg, 0.54 mmol), 5-bromo-2-methylsulfonyl-pyridine (CAS no. 98626-95-0) (140 mg, 0.59 mmol), cesium carbonate (350 mg, 1.08 mmol) and bromotris(triphenylphosphine)copper(I) (101 mg, 0.11 mmol) in DMA (5 mL) was stirred in a microwave reactor at 160° C. for 6 hours. Ethyl acetate (50 mL) was added and the mixture washed with water (50 mL), brine (50 mL), dried (MgSO4) and reduced in vacuo. The crude residue was chromatographed on silica, eluting with 10-100% ethyl acetate in isohexane, to give the desired compound (19 mg).
