Process for producing amide derivatives and intermediates therefor
摘要:
A method for producing an amide derivative of the formula [XV] ##STR1## wherein each symbol is as defined in the specification, and an enantiomer thereof, a novel intermediate useful for producing said compound and a production method thereof.The production method of the present invention is extremely easy and simple as compared to the conventional methods, and enables effective production of compound [XV] at high yields, which includes compound [XVI] having an HIV protease inhibitory action. In addition, the novel intermediates of the present invention are extremely useful as intermediates for producing not only the aforementioned compound [XVI] but also compounds useful as X-ray contrast media.
