4-{[Ethyl-(7-nitro-1,2,3,4-tetrahydro-naphthalen-2-yl)-amino]-methyl)-piperidine-1-carboxylic acid tert-butyl ester → 4-{[(7-Amino-1,2,3,4-tetrahydro-naphthalen-2-yl)-ethyl-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester

Participants

Reaction Steps

To a solution of 4-{[ethyl-(7-nitro-1,2,3,4-tetrahydro-naphthalen-2-yl)-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester (490 mg, 1.2 mmol) in ethanol (30 mL) was added 10% palladium on charcoal (50 mg). The solution was shaken on a Parr shaker for 24 h at 55 psi of hydrogen. The solution was filtered through Celite® and concentrated to afford 4-{[(7-amino-1,2,3,4-tetrahydro-naphthalen-2-yl)-ethyl-amino]-methyl}-piperidine-1-carboxylic acid tert-butyl ester as an oil (405 mg) which was used directly.
