Amines 4-tert-butylaniline

The feasibility of this approach was demonstrated with a model library of 36 compounds prepared from a combination of three Boc protected L-amino acids (valine 23, phenylalanine 24, and proline 25) and 12 aromatic amines (3,4,5-trimethoxyaniline (26), 3,5-dimethylaniline (27), 3-benyloxyaniline (28), 5-aminoindane (29), 4-tert-butylamline (30), 4-biphenylamine (31), 1-3-benyloxyani-line (28), 5-aminoindane (29), 4-tert-butylaniline (30), 4-biphenylamine (31), 1-aminonaphthalene (32), 4-tritylaniline (33), 2-aminoanthracene (34),... 

Aromatic primary amines react with lead tetraacetate to give symmetrical azo compounds in varying yields, via hydrazo intermediates." " However, in the case of 2,4,6-tri-tert-butylaniline, reaction with lead tetraacetate in benzene at 5°C led to a mixture of three products, the formation of which can be explained by a ligand coupling process. (Scheme 7.2)...
