Versuchsvorschrift

A solution of methyl ((2-amino-5-methylphenyl)sulfonyl)acetate (Preparation 38, 1.5 g) in glacial acetic acid (20 mL) is added dropwise with vigorous stirring to a mixture of sodium nitrite (0.47 g) in water (6 mL) at room temperature. The mixture is stirred for 1 h. The resulting precipitate is filtered and washed with excess water. The solid is collected and placed under high vacuum overnight to obtain 1.05 g (67%) of the title compound as a green powder. Physical characteristics: MS (ESI−) m/z 253 (M−H).
