50 mg (0.16 mmol) of 2-amino-4-[4-(2-hydroxyethoxy)phenyl]-6-sulfanylpyridine-3,5-dicarbonitrile (Example 10A), 38.9 mg (0.18 mmol) of 4-(chloromethyl)-N-methylpyridine-2-carboxamide hydrochloride (Example 41A) and 53.8 mg (0.64 mmol) of sodium bicarbonate were dissolved in 1 ml of DMF and the mixture was stirred at RT overnight. 30 ml of water were added to the reaction mixture, and the precipitate was filtered off. The precipitate was purified by preparative HPLC (Chromasil, water/acetonitrile+0.1% trifluoroacetic acid).
