Versuchsvorschrift

The title compound is synthesized according to general procedure GP4 starting from 2.0 g (5.8 mmol) 4-[3-(6-amino-pyridin-3-ylethynyl)-2-methyl-pyridin-4-yl]-benzoic acid methyl ester using 11.6 mL (11.6 mmoL) 1 N NaOH in 8 mL THF. After completion of the reaction the pH is adjusted to pH about 5 with 1.0 N HCl. The precipitate is collected by filtration, washed with water and dried under vacuum. The solid is taken up in iPrOH, stirred for a few minutes before the solid is isolated by filtration and dried at 40° C. under vacuum. Yield: 1.9 g (99%).
