Procedure

To a solution of N′-[3-(2-fluoro-4-iodophenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl]-N,N-dimethylformamidine 81 (20.0 g) in N,N-dimethylformamide (150 ml) was added 1,8-diazabicyclo[5.4.0]undec-7-en (14.9 ml) and 4-methoxybenzyl chloride 82 (10.1 ml) at room temperature. The mixture was stirred with heating at 75° C. for 2.5 hrs, 1,8-diazabicyclo[5.4.0]undec-7-en (7.50 ml) and 4-methoxybenzyl chloride (4.00 ml) were added, and the mixture was stirred with heating at the same temperature for 2.5 hrs. After allowing to cool to room temperature, isopropyl alcohol (150 ml) and water (300 ml) were successively added dropwise. The mixture was stirred overnight at room temperature, and the precipitated crystals were collected by filtration and dried to give N′-[3-(2-fluoro-4-iodophenyl)-1-(4-methoxybenzyl)-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl]-N,N-dimethylformamidine 83 (20.2 g, yield 77.8%) as yellow crystals.
