Reaction Steps

A mixture of pyridine (15 ml), diphenyl phosphite (2.34 g), imidazole (0.68 g) and o-chlorophenyldiphenylmethanol (2.36 g) obtained in Example 1 (B) was refluxed for 3 hours. The reaction mixture was treated in the same manner as in Example 1 (C) to give 2.16 g of 1-(o-chlorophenyldiphenylmethyl)imidazole. Yield, 78.3%. M.P., 142°-143° C.
