Preparation of 1,3,5-Tris(aminomethyl)-2,4,6-triethylbenzene from Two Versatile 1,3,5-Tri(halosubstituted) 2,4,6-Triethylbenzene Derivatives

The use of 1,3,5-tris(aminomethyl)-2,4,6-triethylbenzene and the intermediates 1,3,5-tris(halomethyl)-2,4,6-triethylbenzene (halo = bromo and chloro) compounds, have been utilized as scaffolds for many molecular receptors. We report here for the first time a detailed practical synthetic procedure, starting from benzene, and in four straightforward steps, to prepare 1,3,5-tris(aminomethyl)-2,4,6-triethylbenzene, a very versatile molecular scaffold. The added advantage is the limited chromatography in the purification procedure.
