Trichloroacetic Acid → 2,2,2-Trichloro-1-(4-(4-methylpiperazine-1-yl)phenyl)ethanol

Participants

Reaction Steps

1.0 ml (10.00 mmol) of trichloroacetic acid and, in small portions, 1.854 g. (10 mmol) of sodium 2,2,2-trichloroacetate are added at room temperature to a solution of 1.362 g (6.67 mmol) of 4-(4-methylpiperazine-1-yl)benzaldehyde in 13.5 ml of dimethylformamide. The reaction mixture is stirred for 3 hours at room temperature. The solvent is concentrated and the crude reaction product extracted with ethyl acetate. The organic phase is washed using saturated sodium bicarbonate solution. The organic phases are combined, dried on magnesium sulfate and then concentrated to yield 1.760 g (yield=82%) of 2,2,2-trichloro-1-(4-(4-methylpiperazine-1-yl)phenyl)ethanol in the form of a white solid.
