Heteroaryl amines readily undergo Buchwald-Hartwig amination reactions with a range of aryl and heteroaryl bromides at room temperature using t-BuXPhos Pd-precatalyst and NaOt-Bu. The pharmaceutically attractive biaryl amines are generally formed in short reaction times (0.5-16 h) and in good to excellent yields.

nucleophilic sites that are selectively arylated at the CNH2 position are obtained, providing an exceptional tool for rapid delivery of a diverse array of medicinally important CNH(aryl) derivatives of aminoazoles without any protection/deprotection of ring NH bonds. It is first example for the selective CNH2 arylation of 5‐aminoindazole, 4‐aminopyrazole, 5‐aminopyrazole, 9H‐purine‐6‐amine, and 1H‐pyrazolo[3
