Reaction Steps
In 1.2 l of dimethylformamide, 196 g of 2,4,5-trimethoxybenzaldehyde were dissolved, followed by the addition of 241 g of sodium trichloroacetate salt under ice cooling. The resulting mixture was stirred at room temperature for 9 hours. After the reaction, 2 l of water were added to the reaction mixture under ice cooling. The solid so precipitated was collected by filtration, followed by washing with water and diethyl ether, whereby 272 g of 1-(1-hydroxy-2,2,2-trichloroethyl)-2,4,5-trimethoxybenzene were obtained (yield: 86%).
