3.20 g of potassium carbonate and then 0.93 ml of tert-butyl bromoacetate were added to a solution of 2.00 g of 2,6-dimethyl-4-(5-methylsulfanyl-7-propoxyoxazolo[5,4-d]pyrimidin-2-yl)phenol in 20 ml of N,N-dimethylformamide. The mixture was reacted at 60° C. for 1 h and then allowed to cool and poured into water. The precipitate obtained was filtered off with suction and dried under reduced pressure. This gave 2.45 g of the title compound.
