Procedure

A mixture of 2,5-dimethyl-7-(2,4,6-trimethylphenyl)-5H-pyrrolo[3,2-d]pyrimidin-4-ol (1 mmol) in POCl3 (1.3 ml) was heated at reflux until all the starting material were consumed (about 1-3 hours). The mixture was concentrated to dryness. The residue was porued into ice-water and extracted with ethyl acetate. The organic layer was dried and concentrated to dryness to give the title compound.
