Trityl chloride → 4-Methyl-1-trityl-1H-imidazole

Participants

Reaction Steps

A mixture of trityl chloride (17 g), triethylamine (8.5 ml), 4-methylimidazole (5 g) and toluene (40 ml) was stirred at 80° for 4 h and filtered, and the solid material was washed with toluene. It was then partitioned between water and chloroform, and the chloroform solution was separated, dried and combined with the dried toluene filtrate. The combined organic solutions were evaporated to dryness under reduced pressure, and the residue was triturated with diethyl ether to give 4-methyl-1-tritylimidazole, mp. 214°-216°.
