Reaction Steps
The title compound is synthesized according to general procedure GP4 starting from 2.0 g (7.73 mmol) 4-chloro-6-ethyl-5-(6-amino-pyridin-3-ylethynyl)-pyrimidine using 2.1 g (11.6 mmol) 4-methoxycarbonylphenyl boronic acid, 271.3 mg (0.39 mmol) bis-(triphenylphoshine)palladium(II) chloride, 5.7 mL (11.5 mmol) of an aqueous 2 M Cs2CO3 solution and 2 mL EtOH in 5 mL DME. The reaction mixture is stirred for 1 h at 130° C. in the microwave. The reaction mixture is suspended in MeOH and the precipitated product is filtered off and washed with MeOH. After drying 2.25 g (81%) of the desired product are obtained as solid material.
