YieldReaction ConditionsOperation in experiment
93.5% With chlorosulfonic acid; 7-chlorosulfonyl-1,4-benzodioxane-5-carboxylic acid 670 g of chlorosulfonic acid were introduced into a balloon flask provided with a condenser and a thermometer. 173 g of 1,4-benzodioxane-5-carboxylic acid were added in portions with the temperature being maintained at 5°-10° C. The mixture was heated at 55° C. and then cooled and poured into ice. The precipitate was dried off, washed and dried again. 250 g of 7-chlorosulfonyl-1,4-benzodioxane-5-carboxylic acid were obtained (M.P.: 210°-215° C.; yield: 93.5percent).
75% With chlorosulfonic acid; at 70℃; for 3h;Inert atmosphere; Synthesis of 7-(chlorosulfonyl)-2,3-dihydrobenzo[b] [l,4]dioxine-5-carboxylic acid (XIII):To a stirred solution of 2,3-dihydrobenzo[b][l,4]dioxine-5-carboxylic acid XII (0.5 g, 2.77 mmol) was added chlorosulphonic acid (1.2 ml, 16.6 mmol) at 0°C under nitrogen atmosphere and the resulting mixture was heated at 70°C for 3 h. After completion of reaction, the reaction mixture was cooled, quenched with ice and extracted with DCM. The organic layer was dried over Na2S04 and evaporated under reduced pressure to afford product XIII in 75percent yield.
