Reaction Steps

100 ml of acetone are added to a solution of 35.3 g (0.882 mol) of sodium hydroxide in 317 ml of water. Then, at 25° C., 26.5 g (0.083 mol) of 4-bromo-2,2-dimethyl-1-chloro-1-(4-methoxyphenyl)-3-butanone are added dropwise. The mixture is stirred at 25° C. for a further 12 hours, poured onto water and extracted with methylene chloride. The aqueous phase is acidified and extracted again. 12.6 g (69% of theory) of 2,2-dimethyl-3-(4-methoxyphenyl)cyclopropanecarboxylic acid of melting point 115° C. are obtained.
