|Section2= |Section3= |Section7= |Section8= }} 2-Nitroaniline is an organic chemical compound that is chemically described as an aniline carrying a nitro functional group in position 2. It is also classified as an aromatic amine. At ambient temperature and pressure, 2-nitroaniline is an orange solid.〔(Safety data for o-nitroaniline )〕 ==Synthesis== One method of preparing o-nitroaniline is via acetanilide. First, aniline acetylated with acetic anhydride. :C6H5NH2 + (CH3CO)2O → C6H5NHC(O)CH3 + CH3CO2H In the next step, the acetanilide is nitrated: :C6H5NHC(O)CH3 + HNO3 → O2NC6H4NHC(O)CH3 + H2O Finally, the nitroacetanilide is hydrolyzed: :O2NC6H4NHC(O)CH3 + H2O → O2NC6H4NH2 + CH3CO2H
