1-benzyl-5-(2,6-dimethyl-1,5-heptadienyl)imidazole → HCID 14128010, compound

Participants

Reaction Steps

In 10 ml of ethanol was dissolved 0.6 g of 1-benzyl-5-[(E)-2,6-dimethyl-1,5-heptadienyl]imidazole obtained in Reference Example 1. To the solution was added 0.1 g of 10% palladium-carbon, and the mixture was subjected to ctalytic reduction under atmospheric pressure. After a theoretical amount of hydrogen was consumed, the catalyst was filtered off and the filtrate was concentrated under reduced pressure. The residue was recrystallized from hexane, giving the title compound in a yield of 95%.
