Reaction Steps

A solution of 4-(6-cyano-5-methoxy-pyridin-2-yl)-benzoic acid ethyl ester from Example 13d in collidine is treated with LiI and heated at 120° C. for 24 h. The reaction mixture is evaporated, the residue is taken into water and neutralized with 1 N HCl. The resulting precipitate is collected and dried to give 4-(6-cyano-5-hydroxy-pyridin-2-yl)-benzoic acid ethyl ester.
