Versuchsvorschrift

A suspension of 4-amino-6-methoxyquinoline (406a) (2.0 g, 11 mmol) in ethanol-free chloroform (60 ml) was treated with 4-N,N-dimethylaminopyridine (1.4 g, 11.4 mmol) and 1,1′-carbonyl diimidazole (2.6 g, 15.9 mmol). The suspension became clear over 1 hour then precipitation occurred. After a further 2 hours, filtration afforded the product as a white solid which was dried in vacuo (1.8 g, 59%).
