Synthesis process of N, N ', N' '-tripivaloylate-1, 3, 5-triaminobenzaldehyde

The invention provides a synthesis process of N, N ', N' '-tripivaloylated-1, 3, 5-triamino benzaldehyde, which is characterized in that the N, N', N ''-tripivaloylated-1, 3, 5-triamino benzaldehyde is obtained by oxidizing a benzyl carbon-hydrogen bond of N, N ', N' '-tripivaloylated-1, 3, 5-triamino toluene to form an aldehyde group, and the N, N', N ''-tripivaloylated-1, 3, 5-triamino benzaldehyde is obtained by oxidizing a benzyl carbon-hydrogen bond of the N, N ', N' '-tripivaloylated-1, 3, 5-triamino toluene to form an aldehyde group. The synthesis process comprises the following steps: adding N, N ', N' '-tripivaloyloxy-1, 3, 5-triaminotoluene and FeCl3. 6H2O into a proper amount of dimethyl sulfoxide (DMSO) solvent to form a reaction system; transferring the reaction system to an environment of 20-25 DEG C for blue light irradiation, and continuously stirring to enable the reaction to be performed for 18-24 hours; and after the reaction is finished, separating from a reaction system to obtain the N, N
