실험 절차

In an analogous manner to that described above, by the condensation of rac-α-(tert-butoxyformamido)-3-(thiophen-2-yl)propionic acid [Pol. J. Chem. 54(11-12), 2225 (1980)] and (1S,2R,3S)-3-amino-4-cyclohexyl-1-cyclopropyl-1,2-butanediol followed by acidic hydrolysis there was obtained (RS)-α-amino-N-[(1S,2R,3S)-1-(cyclohexylmethyl)-3-cyclopropyl-2,3-dihydroxypropyl]-3-(thiophen-2-yl)propionamide, MS: 381 (M+H)+ as a colourless foam.
