To a stirred suspension of dimethyl-7-chloro-4-hydroxyquinoline-2,3-dicarboxylate (5.00 g, 16.90 mM) and benzylhydrazine dihydrochloride (46.15 g, 236.50 mM) in ethanol (100 mL) was added triethylamine (75.8 mL, 541.0 mM). The mixture was heated to give a brown solution which was refluxed for 40 hours during which time a precipitate formed. The suspension was cooled to room temperature and filtered to give the benzylhydrazine salt of the title compound as an impure yellow solid. Multiple crystallizations from ethanolic hydrogen chloride and methanol gave the title compound (0.370 g, 6%) as a white powder, mp 347-350° C.; MS(CI): 354 (M+H).
