참여 물질

반응 단계

A mixture of intermediate (1-e) (0.087 mol) and intermediate (3-a) (0.087 mol) in acetonitrile (600 ml) was stirred and refluxed for 90 min. The reaction mixture was cooled, and the solvent was evaporated. The residue was partitioned between DCM and water. The organic layer was separated, dried, filtered and the solvent was evaporated. The residue was suspended in DIPE with a drop of ACN, filtered off and dried (vacuum, 40° C.), yielding 30.3 g (80%) of (±)-1,1-dimethylethyl trans-4-[[(4-amino-5-chloro-2,3-dimethoxybenzoyl)amino]methyl]-3-hydroxy-1-piperidinecarboxylate (interm. 4).
