YieldReaction ConditionsOperation in experiment
60.5% With trichlorophosphate; In tetrahydrofuran; 1a 5-Chlorosulfonylisatin To a mixture of isatinsulfonic acid, sodium salt dihydrate (10 g, 35.1 mmol) and 50 mL tetramethylene sulfone was added phosphorus oxychloride (16.5 mL, 177 mmol). The resulting mixture was heated at 60 C. for 3 hours. Cool the mixture to 0 C. and cautiously add 120 mL of water. Filter the resulting green solid and wash with water. Dissolve the solid in 100 mL EtOAc and wash three times with 50 mL of water. The organic layer was dried over MgSO4, filtered and concentrated under reduced pressure to give a yellow solid. The solid was recrystallized from EtOAc/Hexanes to give the title compound as an orange solid (5.2 g, 60.5%). ES (-) MS m/e=344 (M-H).
