Reaction Steps

A diazonium salt synthesized from 4-nitroaniline using the procedure of example 1 (1.4 g, 5.9 mmol) was added portionwise to a solution of 2,4-dimethoxyaniline (0.97 g, 6.3 mmol) in dimethylformamide DMF) (20 ml). The resulting red mixture was stirred for 1.5 h, filtered, and the resulting solid recrystallized from ethyl acetate (EtOAc)/Hexanes to give 1.3 g (70.6%) of Compound 5.
