Participants

Conditions

Temperature: 100 °C

Procedure

A mixture of methyl isobutyl ketone (150 ml), triphenyl phosphite (24.8 g), imidazole (10.9 g) and o-chlorophenyldiphenylmethanol (29.5 g) obtained in Example 1 (A) was heated at 100° C. for 5 hours. The reaction mixture was treated in the same manner as in Example 4 to give 26.9 g of 1-(o-chlorophenyldiphenylmethyl)imidazole. Yield, 78%. M.P., 143°-144° C.

Workup

additionThe reaction mixture was treated in the same manner as in Example 4
