Ethanol → [4-(4-Methyl-piperazin-1-yl)-phenyl]-acetic acid

Participants

Reaction Steps

0.559 g (14.77 mmol) of sodium borohydride is added quickly to 2.294 g (7.35 mmol) of dibenzyl diselenide in 28 ml of ethanol. The reaction mixture is stirred at room temperature for 1 hour. 2.266 g (7 mmol) of 2,2,2-trichloro-1-(4-(4-methylpiperazine-1-yl)phenyl)ethanol and 1.680 g (42.0 mmol) of sodium hydroxide are then added. The reaction mixture is stirred at 35° C. for 24 hours. The solvent is concentrated and the crude product extracted with ethyl acetate after adding a pH 5 aqueous phase. The organic phases are combined, dried on magnesium sulfate and then concentrated to yield 2-(4-(4-methylpiperazine-1-yl)phenyl)acetic acid which is used without additional purification.
