Reaction Steps

A mixture of benzene (20 ml), diphenyl phosphite (5.62 g, 24 mmole), imidazole (2.45 g, 36 mmole) and o-chlorophenyldiphenylmethanol (2.95 g, 10 mmole) obtained in Example 1 (B) was refluxed for 8 hours. The reaction mixture was treated in the same manner as in Example 2 to give 2.72 g of 1-(o-chlorophenyldiphenylmethyl)imidazole. Yield, 79%. M.P., 143°-144° C.
