実験手順
A mixture of ethyl 9-iodo-1-methyl-2,7-dioxo-2,3-dihydro-1H,7H-pyrido[1,2,3-de]quinoxaline-6-carboxylate (Preparation 22, 400 mg) is stirred at 180° C. in 4-chlorobenzylamine (2.0 mL) for 1 h. The mixture is cooled and diluted with acetonitrile to give 412 mg of the title compound. Physical characteristics: M.p. 278-283° C.; 1H NMR (DMSO-d6) δ3.38, 4.55, 5.21, 7.35, 7.39, 7.69, 8.18, 8.76, 10.12. Anal. Found: C, 47.43; H, 3.01; N, 8.32; Cl, 7.14.
