참여 물질

반응 단계

Isoquinolin-5-ol (Aldrich, Cat. #H33207)(0.75 g, 5.2 mmol) was dissolved in acetic acid (20.0 mL) in a Parr shaker bottle. The reaction was degassed with nitrogen, and the platinum dioxide (0.050 g) was added. The reaction was charged to 55 Psi hydrogen and shaken. After shaking for 24 h. the reaction was complete. This was filtered to remove the catalyst and concentrated under reduced pressure give a dark amber 1,2,3,4-tetrahydroisoquinolin-5-ol (0.70 g, 90%) as an oil. Analytical LCMS (M+H)+: m/z=150.1.
