Reaction Steps

3-Cyano-4-fluorobenzene-1-sulfonyl chloride (1.1 g) in 1,4-dioxane (10 mL) at 0° C. was treated dropwise with a 7 M ammonia solution in methanol (3.57 mL) and stirred for 30 minutes. A small amount of solid was removed by filtration and discarded. The filtrate was concentrated, diluted with ethyl acetate, washed with water and brine, dried (MgSO4), filtered, concentrated and triturated with diethyl ether to give the product.
