Reaction Steps

To a solution of 7-(4-chlorobenzyl)-8-(cyclopentyloxy)-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (180 mg, 0.35 mmol) in methanol (10 mL) was added ammonium formate (220 mg, 3.5 mmol) and 5% Pd/C (20 mg). The reaction was refluxed under nitrogen atmosphere overnight. The mixture was cooled and filtered. The filtrate was concentrated to give 8-(cyclopentyloxy)-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (120 mg, 87.6% yield) as white solid. LCMS retention time 1.345 min; LCMS MH+-THP 309.
