反应详情

A mixture of methyl 4-chloro-3,5-dinitrobenzoate (60 g), iodobenzene (36 ml) and copper powder (60 g) is stirred at 145°-155° C for 4-5 hours. After cooling, the resulting solids are extracted with three portions of boiling chloroform (each portion 150 ml), and the combined extracts are, after filtration, evaporated in vacuo. After trituration of the residue with methanol (150 ml) followed by recrystallization from 2-methoxyethanol, methyl 3,5-dinitro-4-phenylbenzoate is obtained with a melting point of 147.5°-148° C.
