実験手順

Methylamine (40% aq solution, 8.25 mL) is added to an ice-cooled mixture of 2-chloro-4-fluoro-5-nitro-benzoic acid (7.00 g, 31 mmol) and 70 mL water. After 2 h additional 0.5 mL methylamine solution is added and it is stirred for additional 3 h. Then 200 mL of water and 47 mL 1N aq HCl are added and the resulting precipitate is filtered off, washed with water and dried.
