Process for the preparation of 7-chloro-1,2,3,4-tetrahydroquinolin-4-one |
| abstract |
Process for the preparation of 7-chloro-1,2,3,4-tetrahydroquinolin-4-one by cyclizing 3-m-chloroanilinopropionic acid by means of an oleum, and desulphonating the resulting aromatic sulphonic acids by means of dilute sulphuric acid. The quinolinone product is useful as a starting material for the preparation of pharmaceuticals. |
