Procedure
2-Bromo-1-(3-fluorophenyl)ethanone (10.9 g, 50 mmol) was added to a solution of 2,4-diaminopyrimidine (3.70 g, 34 mmol) in acetone (185 ml), and the mixture was heated to reflux for 6 h. The cooled suspension was filtered and the precipitate was washed with acetone (50 ml). The solid was re-suspended in water (35 ml) and NH4OHaq. (25%, 50 ml), then it was collected over a glass fiber paper and the filtrate was washed with H2O (75 ml). After drying under vacuum, the product was obtained (5.56 g, 72%) as a yellow solid.
