To this mixture was added a solution of 440 mg (0.894 mmol) 6-butyl-4-iodo-2-methyl-5-[(4-iodophenyl)methyl]pyrimidine in 3 mL pyridine. After 5 minutes, the reaction mixture was cooled to room temperature, diluted with CH2Cl2, filtered through powdered cellulose flock, stripped of solvent in vacuo, and was medium pressure chromatographed on silica gel using 13% EtOAc/hexane to give 306 mg of the title compound, 87% yield.
