With 4-methyl-morpholine; triethylamine; In tetrahydrofuran; ethyl acetate; | <strong>[71420-95-6]3-(N-t-butoxycarbonylaminomethyl)phenylacetic acid</strong> (3.47 g, 13 mmol) was dissolved in 115 ml of tetrahydrofuran and 1.8 ml (26 mmol) of triethylamine was added. The solution was cooled to -15 and 2 drops of N-methylmorpholine and 1.7 ml of i-butylchloroformate were added. The mixture was stirred for 20 minutes at -15 then a cold solution of 3.54 g (13 mmol) of 7-aminocephalosporanic acid in 70 ml of 50% aqueous tetrahydrofuran containing 1.8 ml of triethylamine was added while maintaining the temperature at -20 to -15. The mixture was stirred for three hours then triethylamine was added to bring the pH to 7.0. Ethyl acetate (100 ml) was added, the mixture was acidified to pH 1.5 with 3 N hydrochloric acid, the layers were separated and the aqueous phase was re-extracted three times with ethyl acetate. The extracts were combined, dried (MgSO4) and evaporated to give 7-(3-N-t-butoxycarbonylaminomethylphenylacetamido)cephalosporanic acid. |
