Procedure

In the manner given in Preparation 10, 7-fluoro-5(o-fluorophenyl)-3H-1,4-benzodiazepin-2-yl hydrazine is reacted with chloroacetyl chloride and after 1.5 hours with sodium acetate. The mixture is then refluxed to give 8-fluoro-1-(chloromethyl)-6-(o-fluorophenyl)-4H-s-triazolo[4,3-a][1,4]benzodiazepine. Preparation 13 8-Chloro-1-(chloromethyl)-6-(2,6-difluorophenyl)-4H-s-triazolo[4,3-a][1,4]benzodiazepine
