Reaction Steps

The title compound is synthesized according to general procedure GP4 starting from 2.0 g (8.2 mmol) 4-chloro-6-methyl-5-(6-amino-pyridin-3-ylethynyl)-pyrimidine using 2.2 g (12.3 mmol) 4-methoxycarbonylphenyl boronic acid, 240 mg (1.5 mmol) 287 mg (0.41 mmol) bis-(triphenylphoshine)palladium(II) chloride, 6.1 mL (12.3 mmol) of an aqueous 2 M Cs2CO3 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 to product is filtered off and washed with MeOH. After drying 2.2 g (77%) of the desired product are obtained as solid material.
