New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 138479-53-5, name is 2-[1,2,4]Triazol-1-yl-benzaldehyde belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C9H7N3O
Example 1: 5-[l-tert-Butyl-2-(2-l,2,4-triazol-l-yl-phenyl)-lH-benzimidazol-5-yl]- pyrimidin-2-ylamineTo a solution of 4-(2-Amino-pyrimidin-5-yl)-Nl-ieri-butyl-benzene-l,2-diamine (40 mg, 0.16 mmol) in MeOH (5 mL) are added 2-[l,2,4]triazol-l-yl-benzaldehyde (40 mg, 0.23 mmol) and catalytic amount of L-proline (3.6 mg, 0.031 mmol) at room temperature. The solution is heated to 60C for 12 hours. The solution is cooled down and is concentrated under reduced pressure. The residue is purified by silica gel flash column chromatography with 10% MeOH in CH2CI2 as the eluent to afford the title compound as a pale brown oil. Acetonitrile (3 mL) is added to the oil and the solution is sonicated for 10 seconds. The solution is led to stand at room temperature and the solid that crystallizes out from the solution is collected by filtration (30 mg, 47%). LCMS (ESMS): m/z 411.68 (M++l)
