Reaction Steps
According to a method described in [C. M. Paleos et al., J. Org. Chem. 39(24), 3594, (1974)], 16.8 g (0.1 mole) of 1,3,5-trimethoxybenzene was reacted with 35.0 g of chlorosulfonic acid in 250 ml of chloroform at −5 to 0° C., and after the reaction, the reaction solution was treated after a conventional manner, and 15.2 g of the residue was crystallized from n-hexane, filtered and dried to give 12.6 g of 2,4,6-trimethoxybenzenesulfonyl chloride as a pinkish prism crystal.
