Procedure

Prepared analogously to Example 1 from 2-methoxy-3,4-diaminopyridine and 2-methoxy-4-cyano-benzoic acid. The product mixture obtained is digested with dichloroethane/ethanol (3:1). The undissolved material is filtered off, and the solution is evaporated and boiled with methanolic hydrochloric acid. On cooling, the product crystallizes out in the form of the hydrate.
