Related Products of 27996-86-7, The chemical industry reduces the impact on the environment during synthesis 27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, I believe this compound will play a more active role in future production and life.
L-Proline (1.81 g, 15.6 mmol) was added to a stirring, heterogeneous mixture of 4-(1H-1,2,4-triazol-1-yl)benzaldehyde (13.5 g, 78.0 mmol, Intermediate 82: step a) and 2,2-dimethyl-1,3-dioxane-4,6-dione (11.2 g, 78.0 mmol) in ethanol (520 mL) at 23 C. After 1.5 hours, diethyl 1,4-dihydro-2,6-dimethyl-3,5-pyridinedicarboxylate (19.7 g, 78.0 mmol) was added in one portion. After 16 hours, the ethanol was removed by rotary evaporation at 35 C. to afford a yellow solid. Isopropanol (300 mL) was added and the heterogeneous mixture was stirred for 10 minutes at 23 C. The mixture was filtered and the filter cake was washed with isopropanol (150 mL). The solids were collected and dried under vacuum to provide the titled compound as a white solid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-[1,2,4]Triazol-1-yl-benzaldehyde, other downstream synthetic routes, hurry up and to see.
