実験手順

10 g (0.033 mols) 2 bromo-2(2,6-dichlorophenyl)-acetic acid methyl ester (Example 8) are heated with sodium methylate in methanol (1.6 g Na in 100 ml MeOH) in an autoclave for 5 hours at 150 degrees C. After evaporation of the solvent, the residue is taken up in a water-chloroform mixture. By acidification of the aqueous phase, 3.9 g 2-(2,6-dichlorophenyl)-2-methoxy-acetic acid is obtained. It melts at 119-122 degrees C. after recrystallization from diisopropyl ether.
