摘要:
The crystalline dihydrate and trihydrate forms of the antibiotic 7β-[2′-(R)-2′-phenyl-2′-aminoacetamido]-3-chloro-3-(1-carbadethiacephem)-4-carboxylic acid ("LY163892") are described. These hydrates are antibiotics in their own right, and are valuable intermediates to the corresponding monohydrate form of LY163892.
