Reaction Steps

After 2-chloro-9-(3-methoxycarbonylmethylbenzyl)adenine obtained by Reference example 38 (2.00 g, 6.03 mmol) and sodium acetate (2.95 g, 36.0 mmol) were dissolved in chloroform (100 ml), bromine (4.79 g, 30.0 mmol) was added thereto and the mixture was stirred at room temperature for 5 hours. After removing the solvent, the residue was poured into water and extracted with chloroform. The organic layer was washed with saturated sodium hydrogencarbonate, saturated sodium hydrogensulfite and saturated brine in that order, dried over anhydrous magnesium sulfate and concentrated to give the captioned compound (1.78 g, 4.34 mmol, yield: 72%) as a brown solid.
