PROCESS FOR THE PREPARATION OF AN ANTICONVULSANT COMPOUND

摘要

The invention provides a novel method for the preparation of intermediates useful in a process designed to obtain known 1,2,4-triaminobenzene compounds, and in particular a specific compound thereof having known anticonvulsant activity. Unlike known methods, the novel method does not require advance protection of the amino groups present on the substrate.
