Thionyl Chloride → 3-[(2,2,2-Trichloroethoxy)carbonylamino]benzoyl chloride

Participants

Reaction Steps

To a toluene solution (10 ml) of 1.0 g of 3-[(2,2,2-trichloroethoxy)carbonylamino]benzoic acid produced in Example 9-1 was added 2 ml of thionyl chloride, and the resultant mixture was stirred at 100° C. The solvent was distilled off under reduced pressure, and the residue was dissolved in toluene. The solvent was again distilled off under reduced pressure to obtain 1.0 g (yield 95%) of the title compound as a solid.
