Reaction Steps
A 18-mL vial was charged with 4-chloro-2-(5-chloro-2-thienyl)-5-ethyl-6-methyl-pyrimidine (87 mg, 0.318 mmol, 1.05 eq.), 5-amino-2-bromo-benzoic acid (65 mg, 0.3 mmol, 1 eq.). AcOH (1 ml) and 4 N HCl in dioxane (5 drops). The resulting mixture was stirred under Ar at 110° C. for 2 hr. After cooling to rt, The volatile material was removed under reduced pressure and the residue was treated with dichloromethane to give the title compound (105 mg, 77% yield).
