실험 절차
The resultant crude mixture containing protected cefadroxil is worked up by treatment with a mixture of ice water and concentrated HCl. The phases are separated and Reextraction with water/HCl is carried out. The combined aqueous phases are treated with additional DMF, the solution is filtered and left overnight in a refrigerator. Crystalline cefadroxil dimethylformamide solvate is obtained, filtered off, washed with acetone and dried. Yield: 83%.
