Reaction Steps

25 ml of 25% NH4OH were added dropwise while cooling in an ice bath to a solution of 7.3 g of p-methoxybenzenesulfonyl chloride in 50 ml of tetrahydrofuran. Subsequently, the reaction mixture was stirred vigorously for 30 minutes at 70° C. (bath temperature). Thereafter, the tetrahydrofuran was distilled. The residue was extracted with ethyl acetate. There was obtained p-methoxybenzenesulfonamide which was converted into the potassium salt as described in Example 50.
