To a solution of 14.5 g (72.5 mmol) of purified 3-(3-trifluoromethylphenyl)propargyl alcohol in 50 mL of 2-propanol was added 0.38 g of 10% Pd/C (Selcat Q6). The reaction mixture was subjected to hydrogenation at a temperature of 42-45°C and a pressure of 5 bar until all feedstocks were completely converted (about 5 hours). Upon completion of the reaction, it was filtered to remove the catalyst and the catalyst was washed with a small amount of 2-propanol. Subsequently, the filtrate was concentrated by evaporation under reduced pressure. The crude product obtained (14.5 g, 100.0%) was purified by distillation under reduced pressure, resulting in 10.5 g (yield: 72.1%) of the target product 3-(3-trifluoromethylphenyl)propanol as an almost colorless oil (boiling point: 58-60 °C/1.1-1.5 mbar).
