ABSTRACT:
The present invention relates to a novel method for producing a compound of the formula [11]wherein R is an optionally substituted aromatic hydrocarbon group, an optionally substituted alicyclic hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted condensed heterocyclic group, which is useful as a therapeutic agent for diabetes. The method of the present invention is an industrially utilizable method that enables efficient production of the objective compound [11] from β-methyl L-aspartate via an important intermediate compound [6]wherein R is as defined above, at high yield.
