Versuchsvorschrift

To a mixture of 6-Chloro-4,5-diaminopyrimidine (0.70 g, 4.84 mmol) and 3-chlorobenzoic acid (0.76 g, 4.84 mmol) in the flask was added phosphoryl chloride (40.0 mL), and the resulting mixture was stirred for 16 h at 100° C. The reaction mixture was evaporated to remove excess phosphoryl chloride, and the residue was added to water (20 mL). The precipitate was filtered and purified by flash chromatography (0 to 5% Methanol/DCM) to afford the title compound (1.28 g, 31%) as a yellow solid. LC/MS: Rt=1.59 min, ES+ 265.0 (FA standard).
