Process for preparation of 7-[alpha-amino (4-hydroxyphenyl) acetamido]-3-substituted-3-cephem-4-carboxylic acid |
| abstract |
A process for preparation of 7-[D-α-amino-α-(4-hydroxyphenyl)acetamido]-3-(1-propen-1-yl)-3-cephem-4-carboxylic acid viz. Cefprozil of formula (I) igh purity, substantially free of impurities, n nwhich comprises preparation of mixed acid anhydride by selecting the sequence and temperature of addition of the reagents and its subsequent condensation with a protected 7-APCA; followed by hydrolysis, isolation and purification to give Cefprozil of formula (I) in the form of a monohydrate. |
