Reaction Steps

The compound prepared in Example 214 (0.44 g), 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.25 g), 4-aminopicolinic acid (0.18 g), 1-hyroxybenzotriazole hydrate (0.20 g) and N-ethyl-N-isopropylpropan-2-amine (1.2 ml) were combined in dimethylacetamide (8 mL) and the reaction was allowed to stir 2 days. The reaction was diluted with ethyl acetate and washed with aqueous sodium bicarbonate and brine. The organic phase was dried over magnesium sulfate, filtered, concentrated and purified by column chromatography using an eluant (2 to 6% methanol/dichloromethane) to provide the title compound (0.05 g) with the following physical data.
