実験手順

Benzyloxy-acetic acid 5-chloro-2-(2,4-dichloro-phenoxy)-phenyl ester 4 (5 grams) was dissolved in methanol (50 mL) in a pressure vessel, palladium on carbon (5%, 5 grams) was added and the mixture was stirred under an atmosphere of hydrogen (4 Kg) for 4 hours. The catalyst was removed by filtration and the methanol was distilled off to yield crude 5.
