Versuchsvorschrift

8-chloro-5-(2-chlorophenyl)-1,2-dihydro-7-methoxy-3-methyl-pyrazolo[3,4-b][1,4]benzodiazepine (IVy) was prepared by reacting 0.0012 moles of (2-amino-4-chloro-5-methoxyphenyl)(2-chlorophenyl)-methanone (Xy) with 4-amino-5-chloro-3-methyl-1-(2-propenyl)-1H-pyrazole (XIII), and subsequent dealkylation of the intermediate, 8-chloro-5-(2-chlorophenyl)-1,2-dihydro-7-methoxy-3-methyl-1-(2-propenyl)-pyrazolo[3,4-b][1,4]benzodiazepine (XIVy) with diisobutylaluminum hydride in a manner analogous to Example 72. MH+/Z=373.
