실험 절차
A stirred solution of 2-chloro-5-methylbenzoyl chloride (9.41 g, 49.8 mmol) in chlorobenzene (14 ml) at 80° C. was treated with aluminum chloride (7.32 g, 54.9 mmol) in portions over 15 minutes. The mixture was stirred 15 hours at 80° C., cooled, quenched by addition of ice and concentrated hydrochloric acid (5.0 ml) and extracted with diethyl ether (2×50 ml). The combined extracts were washed with water, dried over anhydrous magnesium sulfate, and evaporated under vacuum. The residue was crystallized from n-hexane to provide 10.4 g (79%) of 3-(4-chlorobenzoyl)-4-chlorotoluene, m.p. 85°-90° C. Recrystallization raised the melting point to 90°-92° C.
