Versuchsvorschrift

Reaction under nitrogen atmosphere. Sodiumhydride (0.3 mol) was added to a solution of 1,1-dimethylethyl trans-3-hydroxy-4-[[[(4-methylphenyl)sulfonyl]oxy]methyl]-1-piperidinecarboxylate [described in WO-00/37461 as intermediate (1-c)] (0.27 mol) in THF (1300 ml). The mixture was stirred for 30 minutes. Methyliodide (0.54 mol) was added and the resulting reaction mixture was stirred for 90 minutes. A small amount of water was added. The solvent was evaporated and the residue was partitioned between water and DCM. The organic layer was separated, dried, filtered and the solvent was evaporated, yielding 1,1-dimethylethyl trans-4-[[[(4-methylphenyl)sulfonyl]oxy]-methyl]-3-methoxy-1-piperidinecarboxylate (intermediate 62).
