실험 절차

To a solution of 8-bromo-7-(4-chlorobenzyl)-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (100 mg, 0.195 mmol, intermediate 14) in DMF (5 mL) was added 6-methylpyridin-3-ol (24 mg, 0.22 mmol) followed by potassium carbonate (76 mg, 0.55 mmol) and the mixture was stirred at 85° C. for 3 h. The mixture was cooled and partitioned between ethyl acetate and brine. The layers were separated and the organic layer was washed with saturated aqueous ammonium chloride, dried and concentrated to give 7-(4-chlorobenzyl)-3-methyl-8-(6-methylpyridin-3-yloxy)-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (79 mg, 75% yield) as yellow solid. LCMS retention time 2.297 min; LCMS MH+-THP 456.
