Cesium carbonate (782 mg, 2.4 mmol) was added to a solution of 3-hydroxy-5-[(1-methylethyl)oxy]-N-(5-methylpyrazin-2-yl)benzamide (230 mg, 0.8 mmol) and 2,3-dichloro-5-(pyrrolidin-1-ylcarbonyl)pyridine (234 mg, 0.96 mmol) in acetonitrile (5 mL) and the stirred mixture heated in a microwave reactor at 120° C. for 2 hours. The mixture was cooled to RT and the acetonitrile evaporated in vacuo. The residue was partitioned between water (25 mL) and ethyl acetate (50 mL), the organic layer washed with brine, dried (MgSO4) and evaporated to a residue which was chromatographed on silica, eluting with 75% ethyl acetate in isohexane, to give the desired compound (290 mg).
