Reaction Steps

A solution of 17.2 g. of 2-benzoylimidazole (A. Sonn and P. Greif, Ber. 66 (1933), 1900) in 100 ml. of anhydrous tetrahydrofuran was added drop-wise to a Grignard reagent prepared from 5.8 g. of magnesium and 45.9 g. of 1-bromo-4-chlorobenzene in 150 ml. of anhydrous tetrahydrofuran. The reaction mixture was boiled under reflux for half an hour, cooled and poured onto a mixture of ice and hydrochloric acid. The solution was neutralized with concentrated ammonia solution and extracted with tetrahydrofuran. The organic solvents layer was dried and concentrated; the residue was crystallised from isopropyl alcohol. Melting point of the product was 162°-165° C.
