Reaction Steps

1-Ethyl-6-fluoro-1,3-dihydro-5-nitro-2,1-benzisothiazole 2,2-dioxide (Compound B from Example 1, Step C, 1.0 g), was suspended in tetrahydrofuran (20 mL) with 10% palladium on carbon (100 mg). The suspension was placed in Parr® shaker and treated with 50 psi (3.45×105Pa) of hydrogen overnight. The catalyst was then filtered off through diatomaceous earth (Celite®), and the filtrate was evaporated under reduced pressure to give the title compound of Step A as a brown solid (0.510 mg). 1H NMR (CDCl3): δ 6.92 (dd,1H), 6.04 (dd,1H), 4.08 (s,2H), 3.80 (br s,2H), 3.64 (q,2H), 1.32 (t,3H).
