Reaction Steps
324,8 g (1 mole) of 4,4,4-tribromobutyric acid is added to 600 g of thionylchloride and 1 ml of dimethylformamide and the whole is heated at first for 2 hours at 40° C. and subsequently for 3 hours at 75° C. Then the excess of thionyl chloride is evaporated and the residue is distilled in vacuo. 360 g (95% of theory) of 4,4,4-tribromobutyric acid chloride, b.p. 71°-73° C./0,05 torr, is obtained.
