Procedure
In the manner given in Example 2, 7-fluoro-5-(o-chlorophenyl)-3H-1,4-benzodiazepin-2-yl hydrazine was reacted with dibromoacetyl chloride and after 1.5 hours with sodium acetate, then the mixture was refluxed to give 8-fluoro-1-(dibromomethyl)-6-(o-chlorophenyl)-4H-s-triazolo-[4,3-a][1,4]benzodiazepine.
