Procedure

The above compound, 9-allyl-1-propyl-8-thiophen-2-yl-1,9-dihydro-purin-6-one (0.100 g, 0.33 mmol) and Wilkinson's catalyst were taken in acetonitrile:water (6:1, 7 ml) and refluxed for 5 h at 100° C. Solvent was removed and further purified by preparative TLC to get pure 1-propyl-8-thiophen-2-yl-1,7-dihydro-purin-6-one (9 mg, 10%).
