Related Products of 3034-50-2, The chemical industry reduces the impact on the environment during synthesis 3034-50-2, name is Imidazole-4-carbaldehyde, I believe this compound will play a more active role in future production and life.
A 1 litre flask was charged with 1 H-imidazole-4-carbaldehyde (14 g, 146 mmol) and absolute ethanol (240 mL). Then 2-(benzylamino)ethanol (20.8 mL, 146 mmol) wasadded and the white suspension turned slowly into a yellow solution after 3 h The mixture was then cooled in an ice-bath and sodium triacetoxyborohydride (93 g, 437 mmol) was added portionwise. The mixture was then stirred overnight at room temperature. Water was added and the mixture was partially concentrated. After neutralising to pH -7 with 1 M aqueous NaOH, the aqueous phase was rinsed twicewith ethyl acetate, then it was basified further to pH 14. The aqueous layer was then extracted with thrice with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and evaporated to dryness to give the title compound (26.9 g), which was directly used in the next step.1H NMR (ODd3) 67.52 (s, 1H), 7.37-7.18 (m, 6H), 6.87 (s, 1H), 3.69 (s, 2H), 3.68- 3.58 (m, 5H), 2.70 (t, J = 5.1 Hz, 2H).LC/MS: m/z 232 [M+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, Imidazole-4-carbaldehyde, other downstream synthetic routes, hurry up and to see.
