Temperature: 200 °C

Procedure

A mixture of 4-(2-chloro-pyridin-3-yl)-pyrimidine, 4-hydroxy-benzoic acid and Cs2CO3 in DMSO was heated in a microwave (Personal Chemistry, Emrys Optimizer) at 200° C. for 10 minutes. The reaction mixture was cooled to RT and diluted with 60 mL of EtOAc. The product was precipitated from the solution. The mixture was then washed with 20 mL of water twice. The solid was collected by filtration and dried in an oven at 50° C. to afford off white solid as desired product. MS m/z=294 [M+1]+. Calc'd for C16H11N3O3: 293.28.
