Versuchsvorschrift
A solution of 2,6-dichlorobenzenesulfonyl chloride (10.50 g, 42.77 mmol) in 100 mL of pyridine was added into 100 mL of pyridine dropwise while anhydrous ammonia gas was passing through the solution simultaneously for 4 hours at 0° C. The mixture was acidified to pH>1 with 6N aq. HCl, then extracted with ethyl acetate. The combined organic layer was then dried (Na2SO4) and concentrated to give the desired product (8.69 g, 90%). EI-MS (m/z)225.0, 227.1 (M).
