반응 단계
The starting substance is prepared as follows: 15.4 g (0.1 mole) of 2-cyano-quinoline are dissolved in 200 ml of anhydrous ether, and a Grignard reagent prepared from 2.5 g (0.13 moles) of 4-chloro-bromobenzene and 3.16 g (0.13 moles) of magnesium metal are added. The reaction mixture is allowed to stand overnight, thereafter it is poured into a mixture of 15 g of ammonium bromide and ice, acidified with sulfuric acid and the organic phase is separated. After evaporating the ether the product thus-obtained (24 g) is recrystallized from ethanol. The 2-(4-chlorobenzoyl)-quinoline is obtained with a yield of 89%.
