Reaction Steps

To a solution of 7-(4-chlorobenzyl)-1-(4-methoxybenzyl)-3-methyl-8-(3-(trifluoromethoxy)benzoyl)-1H-purine-2,6(3H,7H)-dione (15 mg, 0.025 mmol) in DCM (1 ml) was added TFA (1 ml) dropwise followed by trifluoromethanesulfonic acid (0.25 ml), both at 0° C. The reaction was stirred at 0° C. for 10 min, then stirred at room temperature for 16 h. The reaction was quenched with aqueous saturated sodium bicarbonate and extracted with DCM. The organic phase was washed with water dried over sodium sulfate, filtered and concentrated to give 7-(4-chlorobenzyl)-3-methyl-8-(3-(trifluoromethoxy)benzoyl)-1H-purine-2,6(3H,7H)-dione (10 mg, 83.7%) as yellow oil. LCMS retention time 1.821 min; LCMS MH+ 479.
