Reaction Conditions

Reaction Steps

1.53 g (36.3 mmol) of lithium hydroxide monohydrate are added to a solution of 7.5 g (18.2 mmol) of methyl (Z)-2-methoxy-3-(3-butoxy-4-(trifluoromethanesulphonyloxy)phenyl)acrylate in 50 ml of a tetrahydrofuran/water 10/1 mixture. The reaction mixture is stirred at 68° C. for 5 hours. The reaction mixture is acidified with a 2N hydrochloric acid solution down to pH=1. The reaction mixture is extracted with two times 100 ml of a heptane/ethyl acetate 1/2 mixture. The organic phases are combined and then dried over sodium sulphate. The solvents are evaporated and then the residue is taken up in 30 ml of pentane. 4.7 g of (Z)-3-(3-Butoxy-4-(trifluoromethane-sulphonyloxy)phenyl)-2-methoxyacrylic acid are obtained in the form of a white solid.
