실험 절차

1,49 Grams of the ester prepared according to (a) are stirred in 30 ml of trifluoroacetic acid, at room temperature. The hydrolysis is followed by TLC; at the end the excess of CF3 --COOH is evaporated in vacuo and the residue is crystallized from acetic acid/ethanol. The title product is identical with a sample prepared according to EP 54812.
