2-Thiophenesulfonamide Use and Manufacturing

Methods of Manufacturing

Preparation of thiophene-2-sulphonamide[00156] Thiophene-2-sulfonyl chloride (0.5 g, 2.74 mmol) was added in a 25 percent ammonium hydroxide solution (5 ml_, 33.45 mmol) refluxing at 50 °C, and stirred for 15 minutes. The reaction mixture was filtered while boiling and the residue was washed with boiling 25percent ammonium hydroxide aqueous solution. Ammonium hydroxide solution was removed in vacuo until the ammonia smell disappeared and the target compound was re-crystallised from water (0.328 g, 77percent) as a white solid; mp 145 - 146 °C; v
