反応手順

1-Benzyl-5-(2-phenylindan-1-ylidenemethyl)-1H-imidazole was prepared as 1-benzyl-5-(6-methoxy-2-phenylindan-1-ylidenemethyl)-1H-imidazole above except that 2-phen-ylindan-1-one was used as a starting material. In this case after evaporation of the filtrate the residue was dissolved in diluted hydrochloric acid. The product was extracted into dichloromethane. The combined organic phases were washed with water, dried over sodium sulfate and evaporated under reduced pressure. The crude product as its hydrochloride salt was used in the next step without purification.
