Reaction Steps
The starting material, 4,5,6,7-tetrahydro-1H-1,3-diazepin-2-ylhydrazine hydrochloride, is prepared as follows: 4,5,6,7-tetrahydro-2-methylthio-1H-1,3-diazepine (McKay and Kreling. Can. J. Chem. 35 1438 (1957) and hydrazine are added to ethanol, and the solution then heated to yield 4,5,6,7-tetrahydro-1H-1,3-diazepin-2-ylhydrazine hydroidide, melting point 133° -135° C. If the latter compound is treated with silver chloride in aqueous or ethanol solution, the hydrochloride salt is obtained, melting point 192°-193° C.
