We’ll be discussing some of the latest developments in chemical about CAS: 138479-53-5, name is 2-[1,2,4]Triazol-1-yl-benzaldehyde, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a round bottom flask is added 4-(2-amino-4-methoxy-pyrimidin-5-yl)-N^-ieri-butyl- benzene- 1,2-diamine (118 mg, 0.411 mmol) in DMF (4 mL) and water (1 mL), followed by the addition of 2-1,2,4-triazol-l-yl-benzaldehyde (78 mg, 0.45 mmol) and oxone (51 mg, 0.443 mmol). The reaction mixture is stirred at room temperature for 4 hours. Sat. sodium thiosulfate (10 mL) is added. The reaction mixture is diluted with EtOAc. The organic layer is separated, washed with water then brine, dried with Na2S04, filtered and concentrated. The residue is loaded into a silica gel column. The column is eluted with 0- 4% 7M NH3 in MeOH/CH2Cl2. The product fractions are collected and concentrated to afford the title compound (67 mg, 37 %) as a light brown solid. LCMS (ESMS): m/z 441.73 (M++l)
