Reaction Steps
A mixture of 500 mg of 5-bromo-pyridine-2,4-dicarboxylic acid from Example 2, 100 mg of copper sulfate and 20 ml of ammonia solution (d=0.91) is heated at 160° C. in an autoclave for 4 hours. The solution is evaporated to dryness, the solid is heated with a little methanol and the insoluble material is removed from the solution. After 20 hours, a white solid precipitates out at 0° C. and is filtered off and dried.
