Procedure

Into a solution of N-(4-(5-((benzyl(methyl)amino)methyl)-1-(2,6-difluorobenzyl)-1,2,3,4-tetrahydro-2,4-dioxo-3-phenylthieno[2,3-d]pyrimidin-6-yl)phenyl)-N′-methoxyurea (7.7 g, 11.53 mmol) in THF (200 ml) which was cooled with a dry ice-acetone bath was added α-chloroethyl chloroformate (1.7 ml, 11.64 mmol). The temperature of the mixture was elevated up to room temperature, and the mixture was stirred for 2.5 hours. The reaction mixture was diluted with saturated aqueous solution of sodium bicarbonate and extracted with chloroform. The organic layer was washed with saturated aqueous solution of sodium chloride, dried over magnesium sulfate and concentrated under reduced pressure.
