Reaction Steps

To a stirred and refluxed Grignard complex, previously prepared starting from 9 parts of bromoethane, 2.16 parts of magnesium and 140 parts of 1,1'-oxybisethane were added dropwise 11.3 parts of 1-(1,2,3,4-tetrahydro-1-naphthalenyl)-1H-imidazole-5-carboxaldehyde. Upon complete addition, stirring was continued for 2 hours at room temperature. The reaction mixture was poured into water and treated with a sodium hydroxide solution. The separated organic layer was washed with water, dried, filtered and evaporated, yielding 4.6 parts (35.8%) of α-ethyl-1-(1,2,3,4-tetrahydro-1-naphthalenyl)-1H-imidazole-5-methanol as a residue (compound 2.06).
