Reaction Steps
To a 0° C. solution of 2-(2,4-dimethoxybenzyl)-5,5-difluoroisothiazolidine-1,1-dioxide (0.100 g, 0.3 mmol) in methylene chloride (6 mL) was added trifluoroacetic acid (2.182 mL, 29.4 mmol). The resulting red/purple solution was stirred at 0° C. for 3.5 hrs and concentrated in vacuo. The crude material was purified by silica gel chromatography (30-75% ethyl acetate/hexanes) to give a tan oil (0.036 g). 1H NMR (CDCl3, 300 MHz) δ 4.78 (br s, 1H), 3.46-3.40 (q, 2H, J=6.6 Hz), 2.79-2.65 (m, 2H). 19F NMR (CDCl3, 282 MHz)-105.96-106.07 (t, J=15.4 Hz).
