Reaction Steps
7.7 g (33 mmol) of 4-chloro-3,3-dimethyl-2,3-dihydro-1,2-benzoisothiazole 1,1-dioxide, 8.25 ml (55 mmol) of bromoacetaldehyde diethyl acetal and 7.0 g of potassium carbonate were taken up in 100 ml of dry DMF and stirred at 120° C. for 5 h. The reaction mixture was poured into ice-water and then extracted with ethyl acetate, and the organic phase was washed with water and dried over sodium sulfate. The solvent was removed under reduced pressure, the crude product was purified by column chromatography. 7.5 g (65%) of the product were obtained as an oil in this way.
