実験手順

A suspension of 2,6-dichloro-3-nitrotoluene (6.0 g, 29 mmol) in 50% methanolic ammonia (60 mL) was stirred at 130° C. (340 lb pressure) for 18 hours. The autoclave was cooled to -30° C., opened, and the precipitate was filtered off and washed with methanol to give 4.14 g (76%) of 3-chloro-2-methyl-6-nitrobenzenamine.
