A solution of 15,0 g 2-(methylthio)-5-phenyl-7-chloro-3H-1,4-benzodiazepine [cf. G. A. Archer et al., J. Org. Chem. 29, 231 (1964)] and 11,5 g 2-(p-methoxybenzyloxy)-acetic acid-hydrazide in 100 ml hexamethyl-phosphoric acid triamide is heated for 10 hours at 140°. The reaction mixture is worked up analogously to Example 1. The crude product is crystallised from ethyl acetate-petrol ether, whereby 1-[(p-methoxybenzyloxy)-methyl]-6-phenyl-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine M.P. 157°-159° is obtained.
