Reaction Steps

1,2-Bis(carbamoylmethoxy)benzene was prepared by a known method (H-S Kim. et al., (1998) J. Heterocyclic Chem., 35, 177-181). 1,2-Bis(carbamoylmethoxy)benzene (4.4 g) was added to chlorosulfonic acid (13 ml) at 0° C. with good stirring. Chloroform (4 ml) was added and warmed to about 60° C. for 2 hours. The reaction mixture was poured into chopped ice. The precipitates were collected, and washed with cold water. The solids were again washed with acetonitrile, and dried in vacuo to yield the title compound (4.9g).
