Process for the preparation of 4-(1-hydroxy-1-methylethyl)-2-propyl-imidazole-5-carboxylates

摘要

The present invention discloses a process for obtaining 4-(1-hydroxy-1-methylethyl)-2-propyl-imidazole-5-carboxylate by the reaction of 4,4-dimethyl-2-propyl-4,6-dihydrofuro[3,4-d]imidazole, or its hydrolysis product, or its ring-opening product, with alcohol under appropriate catalytic conditions. Furthermore, the present invention also provides a process for obtaining high purity 4,4-dimethyl-2-propyl-4,6-dihydrofuro[3,4-d]imidazole.
