Reaction Steps

The title compound is synthesized according to general procedure GP8 starting from 4.0 g (10.2 mmol) 4-[5-(6-amino-2-methyl-pyridin-3-ylethynyl)-6-ethyl-pyrimidin-4-yl]-2-fluoro-benzoic acid methyl ester using 1.29 g (30.7 mmoL) LiOH in 40 mL water and 200 mL THF. The reaction mixture is stirred over night at 50° C. The THF is removed under reduced pressure and the residue is taken up in water. Aqueous 1 M HCl is added until pH 5-6 is reached. The precipitated product is filtered off and washed with water and MeOH. After drying 1.25 g (32%) of the desired product is obtained a solid material.
