Versuchsvorschrift

45.2 Parts of 6-bromo-4-oxo-1,2,3,4-tetrahydroquinoline and 200 parts of dioxane were mixed, and 39.4 parts of phosgene was introduced to the stirred mixture while the temperature was maintained at 20°-25° C. over about 30 minutes. After the introduction, the reaction was effected at 40°-45° C. for 2.5 hours, and thereafter the mixture was treated as in Example 37 (a) to obtain 55.9 parts of 6-bromo-4-oxo-1-chloroformyl-1,2,3,4-tetrahydroquinoline.
