実験手順

5-(2-chlorophenyl)-1,2-dihydro-8-methoxy-7-(1-methylethoxy)-3-methyl-pyrazolo[3,4-b][1,4]benzodiazepine (IVjj) was prepared by reacting 0.0023 moles of (2-amino-4-methoxy-5-(1-methylethoxy)phenyl)-(2-chlorophenyl)-methanone (Xjj) with 4-amino-5-chloro-3-methyl-1-(2-propenyl)-1H-pyrazole (XIII), and subsequent dealkylation of the intermediate, 5-(2-chlorophenyl)-1,2-dihydro-8-methoxy-7-(1-methylethoxy)-3-methyl-1-(2-propenyl)-pyrazolo[3,4-b][1,4]benzodiazepine (XIVjj) with diisobutylaluminum hydride in a manner analogous to Example 72. MH+/Z=397.
