反应详情

Nitrogen was passed through a stirred suspension of (Z)-3-(2,3-dimethoxyphenyl)-2-propenoic acid (14,67 g) in 400 ml of methanol during 15 minutes. Then 1.4 g of 10% palladium on activated carbon were added and a stream of hydrogen was passed through the reaction mixture for 16 hours. After removing the palladium catalyst by filtration, the filtrate was evaporated to yield 14.2 g of 3-(2,3-dimethoxyphenyl)-propanoic acid, M.S. (C.I.) (MZ): 211 [M+H]+.
