Procedure
A mixture of 7.25 grams (23.0 m moles) of 7-chloro-3-methyl-(methylthio)-5-phenyl-3H-1,3,4-benzotriazepine (Example 27), 4.8 grams (65 moles) of acethydrazide, and 100 ml of n-butanol was stirred and refluxed under nitrogen for about 17 hours. The solvent was removed in vacuo on a rotary evaporator. The residue was dissolved in methylene chloride. The resulting solution was washed with water, dried with magnesium sulfate, and concentrated in vacuo. The residue was dissolved in a minimum amount of warm carbon tetrachloride. The solution was cooled and seeded with product. The precipitate was collected, washed with cold carbon tetrachloride, and air dried to yield the title compound as a yellow solid. The melting point was found to be 224.5°-227.5° C. The structure was confirmed by elemental analysis.
