Reaction Steps

324.8 g (1.0 mol) of 4,4,4-tribromobutyric acid are warmed with 600 g of thionyl chloride and 1 ml of dimethylformamide, first for 2 hours at 40° C. and then for 3 hours at 75° C. The excess thionyl chloride is then distilled off and the residue is rectified under a high vacuum. 326.0 g (95% of theory) of 4,4,4-tribromobutyric acid chloride with a boiling point of 71° to 73° C./0.05 mm Hg are obtained.
