Procedure
To a solution of 2.00 g of 2,6-dimethyl-4-(5-methylsulfanyl-7-propoxy-oxazolo[5,4-d]pyrimidin-2-yl)-phenol in 20 ml of N,N-dimethylformamide was added 3.20 g of potassium carbonate, followed by 0.93 ml of tert-butyl bromoacetate. The mixture was reacted for 1 h at 60° C., then allowed to cool and poured onto water. The resulting precipitate was collected by filtration with suction and dried in vacuo. 2.45 g of the title compound were obtained.
