Reaction Steps

A solution of 18.6 g of p-methylbenzoyl chloride in 30 ml of methylene chloride is added dropwise, over a period of 15 minutes, to a solution, stirred at room temperature, of 22.4 g of 1-[2-(4-chlorophenyl)-ethyl]-piperazine and 12.1 g of triethylamine in 200 ml of methylene chloride. The reaction mixture is stirred overnight at room temperature. The reaction solution is diluted with 100 ml of methylene chloride, washed with 2N NaOH and with water, dried over sodium sulphate and concentrated to dryness by evaporation. The residue is recrystallised twice from alcohol. 1-[2-(4-chlorophenyl)-ethyl]-4-(4-methylbenzoyl)-piperazine having a melting point of 105°-106° is thus obtained.
