Water → alpha-(p-Chlorophenyl)-1-methyl-alpha-phenylimidazole-2-methanol

Participants

Reaction Steps

A solution of 25.5 g (0.08 mol) of 20% butyl lithium in n-hexane in 50 ml. of anhydrous diethyl ether was added at room temperature to a solution of 5 g (0.06 mol) of 1-methylimidazole in 50 ml. of anhydrous diethyl ether. The reaction mixture was stirred for one hour and then a solution of 15.6 g (0.07 mol) of 4-chlorobenzophenone in diethyl ether was added dropwise. The reaction mixture was stirred for 3 hours and it was then poured into a mixture of ice and water. The solid matter was filtered off and crystallised from ethanol. α-(p-Chlorophenyl)-1-methyl-α-phenylimidazole-2-methanol was obtained. Melting point 185°-186° C.
