In the title compound, C 11 H 14 N 2 O, the diazepine ring adopts a skewed boat conformation. The molecule is stabilized by N-HÁ Á ÁO intermolecular hydrogen bonds, forming a zigzag chain parallel to the b axis.
Pyrromethenones 3 have been reduced with sodium dithionite to give 5(2H)-dipyrrylmethanones 4 in very good yields. Some ofthe conditions to optimize this reduction have been studied. ## Reaktivitat von Pyrrolpigmenten, VlII'). -Darstellung von 5(2H)-Dipyrrylmethanonen aus S(1H)-Pyrromethenonen du
In the molecule of the title compound, C 9 H 9 N 3 O, the dihedral angle between the planar rings is 7.49 (3) . In the crystal structure, intermolecular N-HÁ Á ÁO hydrogen bonds link the molecules into dimers, which may be effective in the stabilization of the crystal structure.
