Procedure

The title compound is synthesized in analogy to general procedure GP4 starting from 1.2 g (4.63 mmol) 4-chloro-6-ethyl-5-(6-amino-pyridin-3-ylethynyl)-pyrimidine using 1.0 g (5.6 mmol) 4-methoxycarbonyl-3-pyridyl boronic acid, 163 mg (0.23 mmol) bis-(triphenylphoshine)palladium(II) chloride, 7.0 mL (13.9 mmol) of an aqueous 2 M Cs2CO3 and 2 mL MeOH in 10 mL DME. The reaction mixture is stirred over night at 80° C. The reaction mixture is poured on water and washed with DCM. Aqueous 1 M HCl is added to the aqueous phase until pH 5 is reached. The precipitated product is filtered off and washed with water and methanol. After drying 290 mg (13%) of the desired product are obtained a solid material which is used for the next step without further purification.
