Reaction Steps

The title compound is synthesized according to general procedure GP8 starting from 3.3 g (8.4 mmol) 4-[5-(6-amino-pyridin-3-ylethynyl)-6-ethyl-pyrimidin-4-yl]-2-chloro-benzoic acid methyl ester using 1.06 g (25.2 mmoL) LiOH in 20 mL water and 100 mL THF. The reaction mixture is stirred over night at 50° C. The solvent 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 2.5 g (89%) of the desired product are obtained as solid material.
