32673-41-9, A common heterocyclic compound, 32673-41-9, name is 4-Imidazolemethanol hydrochloride, molecular formula is C4H7ClN2O, 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.
1. Methyl 5-tert-butyl-2-hydroxy-3-[(1H-imidazol-4-yl)methyl]-benzoate hydrochloride. 50 g of 1H-imidazole-4-methanol hydrochloride are reacted with 60 g of methyl 5-tert-butyl-2-hydroxybenzoate in 150 ml of concentrated sulfuric acid at 20 C. for 21 hours. The reaction mixture is then cautiously decomposed on ice. The solid product is filtered off, purified by chromatography and then converted into its hydrochloride. 1.1 g of methyl 5-tert-butyl-2-hydroxy-3-[(1H-imidazol-4-yl)methyl]-benzoate hydrochloride is obtained. Yield: 2.8%. M.P.: 185-186 C. NMR (DMSO): delta 1.3(9H,s), 3.45(3H,s), 4.1(2H,s), 7.3(1H,s), 7.75(2H,m), 9.0(1H,s), 10.5 to 13,0 (3H).
The synthetic route of 32673-41-9 has been constantly updated, and we look forward to future research findings.
