1-Benzyl-4-(2-benzyloxyphenyl)-4-piperidinol → 4-(2-Hydroxyphenyl)piperidin-4-ol

Participants

Reaction Steps

In 100 mL of methanol was dissolved 12 g (32 mmol) of 1-benzyl-4-(2-benzyloxyphenyl)-4-piperidinol. To the resulting solution was added 3 g of 20% palladium hydroxide carbon and the resulting mixture was subjected to catalytic reduction at room temperature for 6 hours under 4 atmospheric pressure. After completion of the reaction, the catalyst was filtered off and the filtrate was concentrated under reduced pressure, whereby 6.7 g (yield: 100%) of 4-(2-hydroxyphenyl)-4-piperidinol was obtained.
