Triethylamine → 2-Chloro-4-(4-methoxypiperidinosulphonyl)benzene sulphonamide

Participants

Reaction Steps

Triethylamine (4.2 ml) and 4-methoxypiperidine (3.15 g) were added to a solution of 3-chloro-4-sulphamoyl-benzene sulphonyl chloride (8.7 g) in acetone (100 ml). The mixture was stirred at room temperature for 1 hour and then poured into 50 ml of N-hydrochloric acid. The resulting product was removed by filtration, washed with water and recrystallized from isopropanol to give the desired compound (8.4 g), m.p. 165°-167°C.
