Participants

Reaction Steps

62 mg (0.416 mmol) of 4-methoxyphenyl isocyanate are added at room temperature to a suspension of 100 mg (0.379 mmol) of 5-aminomethyl-2,3-dimethoxy-7-nitro-quinoxaline in 2 ml of tert-butyl methyl ether, and the mixture is stirred for 3 hours. The suspension is then filtered off, and the filter residue is washed with tert-butyl methyl ether and dried under a high vacuum. The title compound is obtained in the form of a beige solid.
