Reaction Steps

To 87 mL of a solution of 8.7 g of 1-[2-(4-bromophenyl)ethyl]-4-methylpiperazine in THF cooled to −70° C. was added dropwise 21.1 mL of a solution of n-butyllithium (1.6 mol/L) in hexane, and the mixture was stirred at the same temperature for 30 minutes. While the reaction mixture was stirred at the same temperature, 3.6 mL of N,N-dimethylformamide was added dropwise. The mixture was stirred at the same temperature for 30 minutes. The cooling bath was removed, and the mixture was allowed to warm to −10° C., poured into a mixture of 12 mL of 1 N hydrochloric acid and 100 mL of cold water, and subjected to extraction with CHCl3. The obtained extract was dried over MgSO4 and concentrated to give 7.04 g of the title compound (98%).
