実験手順
The above N-(6-amino-2,4-dioxo-3-propyl-1,2,3,4-tetrahydro-pyrimidin-5-yl)-4-benzyloxy-benzamide (1.0 g, 0.0025 mol) and phosphorous pentachloride (0.64 g, 0.0025 mol) were taken in phosphorous oxy chloride (25 ml) and refluxed for 20 hours The mixture was cooled and solvent was removed. The residue was dissolved in water (20 ml) and extracted with DCM. (3×5 ml). The organic layer was washed with sat. NaHCO3 (30 ml) followed by saturated brine solution (2×30 ml) and dried over Na2SO4. Solvent was removed and the residue was further purified by column chromatography to obtain pure 8-(4-benzyloxy-phenyl)-2-chloro-1-propyl-1,7-dihydro-purin-6-one (0.298 g, 30%) as a yellow solid.
