Versuchsvorschrift

7-Chloro-1-ethyl-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carbonyl chloride (22.3 g) in dry dioxan (350 ml) was added slowly to 5amino-1H-tetrazole (7.9 g) and triethylamine (15.1 ml) in dry dioxan (350 ml) and the mixture kept 3 days at room temperature. The solid was collected and dissolved in aqueous dimethylaminoethanol. The solution was filtered and acetic acid was added to the filtrate. The solid that separated was collected and had m.p. above 400°.
