Reaction Steps

A mixture of o-chlorophenyldiphenylmethanol (29.5 g) obtained in Example 1 (B), triphenyl phosphite (24.8 g), imidazole (12.3 g) and methyl isobutyl ketone (150 ml) was heated at 100° C. for 5 hours. The reaction mixture was treated in the same manner as in Example 6 to give 30.0 g of 1-(o-chlorophenyldiphenylmethyl)imidazole. Yield, 87%. M.P., 143°-144° C.
