Electric Literature of 870837-70-0, The chemical industry reduces the impact on the environment during synthesis 870837-70-0, name is 4-(1H-Imidazol-1-yl)-3-methoxybenzaldehyde, I believe this compound will play a more active role in future production and life.
l-(4-Ethynyl-2-methoxyphenyl)-l//-imidazole.A mixture of 4-fiuoro-3-methoxybenzaldehyde (1.0 g, 6.5 mmol) in 20 mL of DMF was treated with 4-methylimidazole (1.0 g, 15 mmol) and warmed to 130 C. Stirred overnight. Diluted with EtOAc, washed with sat’d NaHCO3, dried (Na2SO4), concentrated. Dissolved in 20 mL of MeOH, treated with K2CO3 (2.0 g, 14 mmol) and dimethyl (l-diazo-2-oxopropyl)phosphonate (1.5 g, 7.8 mmol) and stirred overnight. Diluted with DCM and washed with water. Dried (Na2SO4), cone. Chromatography on silica (0-20% MeOH/DCM) gave the desired alkyne:1H NMR (600 MHz, CDCl3) delta7.79 (s, 1 H), 7.18 (t, J= 1.2 Hz, 1 H), 7.16 (d, J= 1.8 Hz, 1 H), 7.15 (m, 2 H), 7.13 (d, J= 1.5 Hz, 1 H).
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-(1H-Imidazol-1-yl)-3-methoxybenzaldehyde, other downstream synthetic routes, hurry up and to see.
