Synthesis

81-07-2

936-16-3

Step 1. Saccharin (10.0 g, 54.6 mmol) was slowly added to a 300 mL THF solution of LiAlH4 (2.24 g, 59.0 mmol) at 0 °C. The reaction mixture was stirred at 15 °C for 3 h in an inert atmosphere. Upon completion of the reaction, EtOAc (100 mL) was slowly added followed by 10% H2SO4 (100 mL). The organic layer was separated and washed with 100 mL of 5% sodium carbonate solution, dried over anhydrous sodium sulfate, filtered and concentrated to afford 1,2-dihydro-1,1-dioxo-1,2-benzisothiazole (4.4 g, 97%).
