Versuchsvorschrift

To a solution of 2-methoxy-4-nitroaniline (5 g) in pyridine (25 ml) at 0° C. was added dropwise methanesulfonyl chloride (3.5 ml). The mixture was left at 0° C. for 1 hour, then brought to RT for 2 h. The mixture was poured onto ice (100 g) and dilute hydrochloric acid (3M, 100 ml), the solid formed was filtered then washed with water and dried to give 2-methoxy-4-nitro-methanesulfonylaminobenzene (7.32 g, 98%) as an off-white crystalline solid.
