80 °C

実験手順

8-bromo-7-(4-chlorobenzyl)-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (0.15 g, 0.35 mmol, intermediate 14) was dissolved in sodium thiomethoxide (5 mL). The reaction was heated at 80° C. overnight. The mixture was cooled and partitioned between ethyl acetate and water. The combined organic layer was dried over sodium sulfate, filtered and concentrated to give a crude product which was used without purification. LCMS retention time 1.875 min; LCMS MH+-THP 395.
