Yield: 47%

Reaction Conditions:

with sodium bicarbonate in sulfuric acid;water;ethyl acetate

Steps:

13 Preparation of 2-amino-9-[2-[bis(2,2,2-trifluoroethyl)-phosphonylmethoxy]ethyl]-6-p-trifluoromethoxyphenylthiopurine (Compound No. 35)
Example 13 Preparation of 2-amino-9-[2-[bis(2,2,2-trifluoroethyl)-phosphonylmethoxy]ethyl]-6-p-trifluoromethoxyphenylthiopurine (Compound No. 35) Zinc powder (3.1 g) was added to a suspension of p-trifluoromethoxybenzenesulfonyl chloride (1.36 ml) in concentrated sulfuric acid (3.4 ml) and water (20 ml), and the suspension was stirred at 0° C. for 18 hours and heated under reflux for 6 hours. The mixture was added with ethyl acetate, washed with water, saturated aqueous solution of sodium hydrogen carbonate, and saturated brine, and then concentrated under reduced pressure to give p-trifluoromethoxybenzenethiol (0.73 g, 47%).
