Method for preparing 2-nitro-4-amino-N-phenylaniline
摘要:
Prepares 2-nitro-4-amino-N-phenylaniline by reacting 4-fluoro-3-nitroaniline at a temperature of at least about 140.degree.C and in a large molar excess of aniline e.g. molar ratio of aniline to 4-fluoro-3-nitroaniline being at least about 5:1.
