Procedure
10 g of 5-(4-chlorobenzyl)-2-(4-methoxy-3,5-dimethylphenyl)oxazolo[5,4-d]pyrimidin-7-ol and 50 ml of phosphorus oxychloride were heated at 90° C. for 5 h. The mixture was then allowed to cool. The solid formed was filtered off with suction, washed with diethyl ether and dried. This gave 10.4 g (99%) of the title compound.
