To 2 ml of a 5.6M solution of dimethylamine in ethanol were added 70 mg (0.19 mmol) of [4-(2-methyl-4-m-tolylethynyl-imidazol-1-yl)-2-oxo-2H-pyridin-1-yl]-acetic acid ethyl ester (Example 13). The reaction vessel was closed and the yellow solution was stirred for 2 days at room temperature. The solution was then evaporated to dryness, the residue was triturated with a small amount of ethyl acetate and the product was filtered off, yielding 59 mg of the title compound as a white solid, MS: m/e=375.3 (M+H+).
