Procedure
In analogy to compound 1.1, a solution of 1.0 g (4.39 mmol) of 5-bromo-2,4-dichloro-pyrimidine in 15 ml of acetonitrile is reacted with 0.27 g (4.74 mmol) of cyclopropylamine in the presence of 0.74 ml (5.3 mmol) of triethylamine. Purification by chromatography (silica gel, ethyl acetate/hexane with ethyl acetate 0-100%) results in 0.76 g (70% of theory) of the product.
