Reaction Steps

2-Chloro-8-isopropyl-7,8-dihydro-5H-pteridin-6-one (28 g; 0.118 mol) in Dimethylacetamide (100 ml) was cooled to −5° C. and iodomethane (8.839 ml; 0.141 mmol)) was quickly added. Then, NaH (7.1 g; 0.177 mmol) was added in portions. After 1 h the reaction mixture was allowed to reach room temperature and was maintained at that temperature until complete conversion of the starting material into the desired product. The reaction mixture was diluted with water and ice and the precipitate formed was filtered and dried in vacuo. 20 g (0.083 mol; 70% yield) of a white powder were obtained.
