Reaction Steps

A mixture of 5-chloro-1,3-dimethyl-1H-pyrazole-4-sulfonic acid {4-[3-cyclopropylmethyl-1-(2-fluoro-benzyl)-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]-phenyl}-amide (300 mg, 0.49 mmol) in methylene chloride (125 mL) and methanol (125 mL) at 25° C. was treated with 10% Pd/C (1.0 g) and sodium acetate (134 mg, 1.22 mmol). The resulting mixture was hydrogenated in a Parr bomb at 50 psi for 24 h. At this time, the reaction was filtered through a pad of celite and was washed with an 8/2 methylene chloride/methanol solution (200 mL). The filtrate was concentrated in vacuo to afford a white solid. This solid was dissolved in a 5/95 methanol/methylene chloride solution. The organics were washed with water (1×25 mL). The aqueous layer was then back-extracted with chloroform (1×50 mL). The combined organics were dried over magnesium sulfate, filtered, and concentrated in vacuo to afford 1,3-dimethyl-1H-pyrazole-4-sulfonic acid {4-[3-cyclopropylmethyl-1-(2-fluoro-benzyl)-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-ylmethyl]-phenyl}-amide (184 mg 65%) as a white solid; (ES)+-HRMS m/e calculated for C28H28FN7O4S (M+H)+ 578.1980, found 578.1987.
