実験手順

5-(2-chlorophenyl)-1,2-dihydro-7-fluoro-8-methoxy-3-methyl-pyrazolo[3,4-b][1,4]benzodiazepine (IVa) was prepared by reacting 0.0014 moles of (2-amino-5-fluoro-4-methoxyphenyl)(2-chlorophenyl)-methanone (Xa) 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-7-fluoro-8-methoxy-3-methyl-1-(2-propenyl)-pyrazolo[3 ,4-b][1,4]benzodiazepine (XIVa) with diisobutylaluminum hydride in a manner analogous to Example 72. MH+/Z=357.
