Reaction Steps

12.0 g (50.0 mmol) of 4-bromo-2,6-dichloroaniline hydrochloride was dissolved in 50 mL of pyridine, 9.90 mL (80.0 mmol) of pivaloyl chloride and 0.61 g (5.0 mmol) of N,N-dimethylaminopyridine were added and the mixture was stirred at 40° C. for 28 hours. Thereafter, substantially the same manner as that in Reference Example (1) was repeated to give 15.7 g of 4-bromo-2,6-dichloro-N-pivaloylaniline (yield: 97%).
