実験手順

To a mixture of N-(trimethylsilyl)imidazole (1.4 g) and titanium tetrachloride (1.6 ml) in dry chloroform (20 ml) a solution of 1-chloro-1-(2,6-dimethylphenyl)ethane (1.7 g) in dry chloroform (10 ml) was added. After stirring for 5 h at room temperature the product mixture was poured onto water, washed with ether and neutralized with sodium hydrogen carbonate. Filtration and extraction with methylene chloride gave 4-[(α-methyl)-2,6-dimethylbenzyl]imidazole, yield 33%.
