Versuchsvorschrift

To a solution of 5-(2,4-dimethoxybenzyl)-4-oxo-5-azaspiro[2.4]heptane-7-carboxylic acid (1.59 g) in chloroform (16 ml) were sequentially added (R)-4-benzyl-2-oxazolidinone (1.11 g), WSC.HCl (1.20 g) and N,N-dimethyl-4-aminopyridine (318 mg) at room temperature, and the mixture was stirred for 4 hours. To this reaction mixture was added water, and the organic layer was separated from the solution, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=2/1) to separate a low-polarity component as the titled compound (1.39 g).
