Participants

Reaction Steps

8.2 grams of the 3,5-dimethyl-1-(p-tolyl)pyrazol-4-acetic acid-ethyl ester, produced by the method of Example (4a), were mixed with a solution of 2.5 grams potassium hydroxide in 15 milliliters water and 15 milliliters ethanol, and the ester saponified and the free acid isolated by the method described in Example (1b). 6.0 grams of 3,5-dimethyl-1-(p-tolyl)-pyrazol-4acetic acid, melting at 119°-121° C. were obtained, representing a yield of 82%.
