Procedure

To a solution of 7-(4-chlorobenzyl)-8-(2-fluoro-5-(trifluoromethoxy)benzyl)-1-(4-methoxybenzyl)-3-methyl-1H-purine-2,6(3H,7H)-dione (71 mg, 0.118 mmol) in DCM (1 mL) was added TFA (0.3 mL) and trifluoromethanesulfonic acid (0.2 mL). The reaction was stirred at room temperature for 16 h. The mixture was concentrated and the residue was partitioned between DCM and aqueous sodium bicarbonate. The organic layer was dried and concentrated to give 7-(4-chlorobenzyl)-8-(2-fluoro-5-(trifluoromethoxy)benzyl)-3-methyl-1H-purine-2,6(3H,7H)-dione (39 mg, 68.4% yield) as a yellow syrup, which was directly without purification. LCMS retention time 1.686 min; LCMS MH+ 483.
