The present invention provides a process for preparing an acid addition salt of a synthetic intermediate for carbapenem antibiotics and a novel acid addition salt of a synthetic intermediate for carbapenem antibiotics obtained from the process. The present invention also provides a process for preparing a carbapenem antibiotic using the acid addition salt. According to the process of the present invention, an acid addition salt of a synthetic intermediate for carbapenem antibiotics can be prepared in a high yield and high purity, without conducting column chromatography. Thus, the process of the present invention can be applied to mass production with an industrial scale. Furthermore, since the acid addition salts have solid forms, they are easy to handle and keep in a manufacturing site.
