反应详情

4.8 Parts of 1-(1,2,3,4-tetrahydro-1-naphthalenyl)-1H-imidazole-5-carboxylic acid are dissolved in 94 parts of warm N,N-dimethylformamide. 0.96 Parts of a sodium hydride dispersion 50% are added portionwise to the thus obtained reaction mixture. Upon complete addition, stirring is continued for 1 hour at room temperature. After the addition of 2.0 parts of 1-chloro-2-methoxyethane, the whole is stirred overnight at 90° C. The reaction mixture is evaporated and the residue is taken up in water. The product is extracted with trichloromethane. The extract is dried, filtered and evaporated, yielding 2.8 parts (46.7%) of (2-methoxyethyl) 1-(1,2,3,4-tetrahydro-1-naphthalenyl)-1H-imidazole-5-carboxylate; mp. 66.8° C. (compound 1.83).
