ethyl (S)-3-[2-(tert-butoxycarbonylamino)-1,2,3,4-tetrahydronaphthalen-7-yl]acrylate → ethyl (S)-3-[2-(tert-butoxycarbonylamino)-1,2,3,4-tetrahydronaphthalen-7-yl]propionate

Participants

Reaction Steps

Ethyl (S)-3-[2-(tert-butoxycarbonylamino)-1,2,3,4-tetrahydronaphthalen-7-yl]acrylate (252 mg) was dissolved in ethanol (10 ml), and 10% palladium on activated carbon (30 mg) was added to the solution, then the resulting mixture was stirred for 3 hours at room temperature under a hydrogen atmosphere. The reaction mixture was filtrated to remove the catalyst, and the filtrate was concentrated in vacuo. Recrystallization of the residue from diisopropyl ether gave ethyl (S)-3-[2-(tert-butoxycarbonylamino)-1,2,3,4-tetrahydronaphthalen-7-yl]propionate (236 mg) having a melting point of 101-102° C.
