A mixture of 4-chloro-6-(3-chlorophenyl)-2-ethylpyrimidine (0.080 g, 0.32 mmol) and 2-(4-aminophenyl)acetamide (0.057 g, 0.38 mmol) and 4M HCl in dioxane (2 drops) in acetic acid (2.5 mL) was heated for 2.5 h at 85° C. After this time, the mixture was cooled to 0° C., neutralized with NaHCO3, extracted with CH2Cl2 (2×30 mL) and EtOAc, dried (Na2SO4), filtered, and concentrated. The residue was purified by silica gel chromatography eluting with methylene chloride and methanol to afford the title compound (0.045 g, 40%) as a white solid.
