Reaction Steps

4,6-Dichloro-2-(3,5-dimethyl-pyrazol-1-yl)-pyrimidine (3.5 g, 14.4 mmol) and 4-chloroaniline (3.7 g, 28.8 mmol) were suspended in water (120 mL) and ethanol (17 mL). Concentrated hydrochloric acid (0.6 mL, 7.2 mmol) was added and the mixture was heated to 88° C. over-night. Additional 4-chloroaniline (918 mg) was added and stirring was continued for six hours. The mixture was cooled to room temperature and diluted with water. The resulting solid was collected by filtration to give [6-chloro-2-(3,5-dimethylpyrazol-1-yl)-pyrimidin-4-yl]-(4-chloro-phenyl)-amine (4.8 g, 99%) as a white solid.
