실험 절차

2,5,6-trimethoxybenzoic acid 5.0 g (0.024 mol) was suspended in 75 ml of CHCl3 and cooled to 0° C. 1.9 ml (0.024 mol) of SO2Cl2 was added under N2 -atm. The reaction was stirred for 2 hr and allowed to slowly attain room temperature. The reaction mixture was diluted 100 ml CHCl3 and washed with 200 ml H2O. The aqueous layer was washed with 50 ml CHCl3 and the combined organic layer was dried (Na2SO4) and the solvent was evaporated. Gave 5.5 g (95%) of 3-chloro-2,5,6-trimethoxybenzoic acid (oil). Mw: 246.7.
