実験手順
To a solution of 7-benzyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-8-(3-(trifluoromethoxy)phenoxy)-3-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (5.3 g, 7.68 mmol) in ethyl alcohol (20 mL) was added concentrated HCl (5 mL). The reaction was stirred at 80° C. overnight. The reaction was concentrated and the residue was neutralized with saturated sodium bicarbonate. This aqueous phase was extracted with ethyl acetate and the phases were separated. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give 7-benzyl-1-(3-hydroxypropyl)-8-(3-(trifluoromethoxy)phenoxy)-1H-purine-2,6(3H,7H)-dione (4.5 g, 100% yield) as white solid. 1H-NMR (DMSO-d6) δ 11.93(s, 1H), 7.62-7.57(t, 1H), 7.44-7.32(m, 8H), 5.42(s, 2H), 4.49-4.46(t, 1H), 3.89-3.86(t, 2H), 3.46-3.41(m, 2H), 1.72-1.65(m, 2H). LCMS retention time 2.560 min; LCMS MH+ 477.
