実験手順

A mixture of 11-cyclopropyl-5,11-dihydro-4-methyl-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (0.5 g) and N-chlorosuccinimide (0.5 g) in carbon tetrachloride (50 mL) was heated under reflux for 6 hours. An additional 0.25 g of N-chlorosuccinimide was added and heating under reflux was continued for 4 hrs more. The mixture was filtered and the solvent was evaporated. The residue was fractionated over silica gel with ethyl acetate/hexane to give the title compound which crystallized from ethyl acetate/ethanol, m.p.>290° C.
