Procedure
A solution of 2.2 g of 1-cyclobutyl-5,6-diamino-2,4-(1H,3H)-pyrimidinedione (X) in 10 ml of acetic acid was refluxed for 2 hours. The solution was evaporated. The received oil was refluxed in 30 ml of 5N NaOH for 1 hour and then neutralized with 5N HCl. The crystals were filtered off and recrystallized from 100 ml ethanol.
