Versuchsvorschrift
To a mixture of methyl-6-amino-1-napthoate (300 mg, 1.5 mmol) and 4-chloro-6,7-dimethoxyquinoline (416 mg, 1.8 mmol) in a 20 mL sealed tube was added isopropyl alcohol (6 mL) and trifluoroacetic acid (287 μL, 3.7 mmol). The reaction vessel was sealed and heated at 90° C. for 1 h before being allowed to cool to ambient temperature. To the resulting thick yellow slurry was added isopropyl alcohol (6 mL). The reaction vessel was sealed and heated at 90° C. for 10 h. The mixture was then cooled to 0° C. and filtered. The resulting solid was washed well with cold CH3OH and dried in vacuo to provide the title compound as a yellow solid. MS (ESI, pos. ion) m/z: 389.3 (M+1). Mass Calc'd for C23H20N2O4: 388.42.
