YieldReaction ConditionsOperation in experiment
35% With chlorosulfonic acid; at -4℃; for 3h; delta-Methyl-thiophene^-carboxylic acid ethyl ester (11.7 mmol) is dissolved in Chlorosulfonic acid (4 ml) at -4 °C and stirred 3 hours. The reaction solution is diluted with dichloromethane and ice water is added. The organic layer is washed with water, dried over MgSO4 and the solvent is removed in vacuo. 4-Chlorosulfonyl-5-methyl-thiophene-2- carboxylic acid ethyl ester is obtained as brown oil in a yield of 35 percent. HPLC (Method A): 3.57 min, LCMS (Method A): 2.48 min, 269.0 m/z(MH+)
