Reaction Steps

3-Octyl-1,2-dihydropyrido[3,4-e]-as-triazine hydrochloride is reacted with acetic anhydride as described in Example 1, and the resulting salt is treated with a solution of sodium hydrocarbonate to obtain 3-octyl-1-acetyl-1,2-dihydropyrido[3,4-e]-as-triazine with a yield of 75%. This compound is reacted with an equimolar amount of fumaric acid in ethanol to obtain the hydrogen fumarate melting at 285°-287° C.
