Reaction Steps

The title compound is synthesized according to general procedure GP8 starting from 200 mg (0.54 mmol) 4-[2-amino-5-(6-amino-pyridin-3-ylethynyl)-6-ethyl-pyrimidin-4-yl]-3-fluoro-benzoic acid methyl ester using 0.81 mL (0.81 mmol) 1 N NaOH in 4 mL THF. After completion of the reaction, the reaction mixture is combined with the mother liquid from the proceeding Suzuki coupling. The pH is adjusted to 4-5 (using 1 N HCl) upon which the product precipitates from the reaction mixture and is isolated by filtration. Yield: 240 mg (58% over two steps).
