Versuchsvorschrift

A solution containing sodium nitrite (0.06 g) and water (1 mL) is cooled to 0° C. before adding a solution of 2-((2-amino-3-thienyl)sulfonyl)-N-(4-chlorobenzyl)-acetamide (Preparation 54, 0.255 g) in hot acetic acid (10 mL) dropwise. The solution is warmed to room temperature and stirred for 30 minutes. The reactionmixture is poured into a beaker containing ice. The crude product is collected by filtration and dried under high vacuum to provide 0.18 g (66%) of the title compound as a brown solid. Physical characteristics: MS (ESI+) m/z 356 (M+H)+.
