1-Benzyl-4-[10-(2-tetrahydropyranyloxy)decyl]piperazine → HCID 19021618, compound

Participants

Reaction Steps

583 mg (1.40 mmole) quantity of 1-benzyl-4-[10-(2-tetrahydropyranyloxy)decyl]piperazine was dissolved in 20 ml of ethanol, and 200 mg of 10 % palladium-carbon was added thereto and the mixture was shaken at 3 atm. for 8 hours under hydrogen atmosphere. The catalyst was filtered off and the filtrate was evaporated under reduced pressure to dryness, giving 375 mg (yield: 82 %) of N-[10-(2-tetrahydropyranyloxy)decyl]piperazine. Then, using N-t-butoxycarbonylphenylglycine and N-[10-(2-tetrahydropyranyloxy)decyl]piperazine was treated in the same procedure as in Reference Examples 1 and 3, giving 384 mg (yield: 75 %) of 1-(2-amino-2-phenylethyl)-4-[10-(2-tetrahydropyranyloxy)decyl]piperazine as a hydrochloride.
