Chakraborty, Shampa published the artcileRapid and efficient synthesis of 2,2-dimethylaminobenzazoles and 2,2-dimethylaminoazoles in a sustainable way, Synthetic Route of 96-20-8, the publication is Materials Research Innovations (2021), 25(2), 90-94, database is CAplus.
Reactions of 2-aminophenol, 2-aminobenzenethiol and other 2-substituted anilines, ethylene amines and amino acid containing 1,2 amino hydroxy groups with TBTU [2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluroniumtetrafluoroborate], easily formed corresponding benzazoles (single crystal X-ray structure) and azoles attached with a di-Me amino group at 2-position via a guanidine intermediate which cyclizes and aromatizes by eliminating one dimethylamino group to afford benzazoles and azoles. The nobality of the synthesis is, single step and can occur at ambient temperature
