Reaction Steps

A mixture of 3-hydroxy-5-[(1-methylethyl)oxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide (250 mg, 0.91 mmol), 2-(azetidin-1-ylcarbonyl)-5-bromopyrimidine (242 mg, 1.0 mmol), cesium carbonate (886 mg, 2.72 mmol) and bromotris(triphenylphosphine)copper(I) (423 mg, 0.45 mmol) in DMA (5 mL) was stirred in a ‘Biotage initiator Microwave’ at 160° C. for 4 hours. The 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 a gradient of 0-10% methanol in ethyl acetate, to give the desired compound (199 mg).
