実験手順

7-benzyl-3-ethyl-1-(3-hydroxypropyl)-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (0.62 g, 1.23 mmol, example 60) was dissolved in ethanol (20 mL); then the mixture was degassed and refilled with nitrogen three times. Ammonium formate (0.5 g, 7.94 mmol) and 10% Pd/C (30 mg) were added. The mixture was again degassed and refilled with nitrogen three times; then it was stirred at 80° C. overnight. The reaction was cooled and filtered. The filter cake was washed with methanol. The filtrate was concentrated to give 3-ethyl-1-(3-hydroxypropyl)-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (0.6 g, 100% yield) as white solid. 1H-NMR (DMSO-d6) δ 7.61-7.57(t, 1H), 7.50(s, 1H), 7.40-7.38(dd, 1H), 7.31-7.29(d, 1H), 4.50(s, 1H), 3.95-3.85(m, 4H), 3.44-3.43(m, 2H), 1.73-1.66(t, 2H), 1.17-1.13(t, 3H). LCMS retention time 1.350 min; LCMS MH+ 415.
