p-Bromochlorobenzene → 3-(4-Chlorobenzoyl)-isoquinoline imine

Participants

Reaction Steps

The starting substance is prepared as follows: To a mixture of 0.62 g (26 millimoles) of metallic magnesium and 8 ml of anhydrous ether a solution of 5.0 g (26 millimoles) of 4-chloro-bromobenzene in ether is dropwise added, the Grignard solution thus-obtained is admixed with 3.1 g (20 millimoles) of 3-cyano-isoquinoline, and the reaction mixture is stirred at room temperature for an hour. The Grignard complex is decomposed with an ammonium chloride solution, the solvent is distilled off and the residue is recrystallized from ethanol. 3.2 g (60%) of 3-(4-chlorobenzoyl)-isoquinoline imine are obtained.
