To a stirred warm (50° C.) solution of 2-amino-6-chlorobenzoic acid (2.00 g, 11.7 mM) in tetrahydrofuran (20 mL) was added bis(trichloromethyl)carbonate (1.20 g, 4.10 mM). A vigorous gas evolution ensued along with the formation of a precipitate. The reaction mixture was allowed to cool to room temperature and the precipitate was collected by filtration and washed with ether. Air drying gave the title compound as a tan solid (2.0 g, 87%); MS(CI): 198 (M+H).
