These common heterocyclic compound, 32673-41-9, name is 4-Imidazolemethanol hydrochloride, 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. Quality Control of 4-Imidazolemethanol hydrochloride
Step A Preparation of 1-triphenylmethyl-4-(hydroxymethyl)imidazole To a solution of 4-(hydroxymethyl)imidazole hydrochloride (35 g) in 250 mL of dry DMF at room temperature was added triethylamine (90.6 mL). A white solid precipitated from the solution. Chlorotriphenylmethane (76.1 g) in 500 mL of DMF was added dropwise. The reaction mixture was stirred for 20 hours, poured over ice, filtered, and washed with ice water. The resulting product was slurried with cold dioxane, filtered, and dried in vacuo to provide the titled product as a white solid which was sufficiently pure for use in the next step.
The synthetic route of 4-Imidazolemethanol hydrochloride has been constantly updated, and we look forward to future research findings.
