Procedure

Sodium nitrite, 1.5 g. (0.022 mol), was added to a solution of 6.2 g. crude 7-chloro-5-(2-chlorophenyl)-1,3-dihydro-2H-1,4-benzodiazepine-2-ylideneacetic acid ethyl ester in 75 ml. of glacial acetic acid. After stirring at room temperature for 20 minutes the reaction mixture was diluted with 200 ml. of water. The precipitated product was collected, washed with water and sucked dry to give crude product. The analytical sample was recrystallized from methylene chloride/ethanol to give light yellow crystals with mp 219°-221°.
