584-13-4, name is 4H-1,2,4-Triazol-4-amine, belongs to Triazoles compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of 4H-1,2,4-Triazol-4-amine
5-(4H-l,2,4-TriazoI-4-ylamino)-4l-methoxybiphenyl-2-carbonitrile (CAB06046) To a solution of 4No.-l ,2,4-triazol-4-amine (3.441 g, 40.928 mmol) in DMSO (40 mL) was added KOtBu (4.593 g, 40.928 mmol). The mixture was stirred for 0.5 hours at room temperature before CAB06042 (4.65 g, 20.468 mmol) was added and stirring was continued for 1 hour. The mixture was poured into crushed ice and neutralized with 2M KHSO4 solution. The precipitate was filtered off and recrystallised from acetone/Et2theta to afford CAB06046 (5.07 g, 85%) as a light yellow crystalline solid.
