Versuchsvorschrift

(2,6-Dichlorophenyl)hydrazine hydrochloride (168 mg, 0.788 mmol) was added to a solution of 6-[(dimethylamino)methylene]-6,11-dihydro-5H-dipyrido[2,3-b:3′,4′-f]azepin-5-one (105 mg, 0.394 mmol, Intermediate E-1) in ethanol (4 mL) and stirred at room temperature. After 30 minutes, the mixture was heated to 60° C. overnight. The reaction was then cooled to room temperature and the major product from the reaction mixture was isolated using preparative LC/MS to provide the desired product as a white powder. 1H NMR (DMSO-d6) δ 8.77 (bs, 1H), 8.45 (bs, 1H), 8.40 (bs, 1H), 8.04 (m, 2H), 7.94 (d, 1H), 7.75 (m, 2H), 7.62 (m, 1H), 6.95 (m, 1H), 6.87 (m, 1H). LC/MS: 380 (M+H)+.
