YieldReaction ConditionsOperation in experiment
7β-amino-3-[(imidazo[l,2-b]pyridazinium-l-yl)methyl]-3-cephem-4-carboxylate hydrochloride (100 g) and 5r-l,3-benzothiazol-2-yl (2Z)-(5-amino-l,2,4-thiadiazol-3- yl)(methoxyimino)ethanethioate (240 g) were added to a mixture of tetrahydrofuran (1.0 L) and water (350 ml) at 150C to 2O0C. A mixture of tributylamine in tetrahydrofuran (70 g/70 ml) was added to the reaction mixture in 20 minutes duration at 150C to 250C to attain a pH of 6.8 to 7.2 and stirred for 5 hours at 250C to 3O0C. The reaction mixture was cooled to 1O0C to 150C and a mixture of dichloromethane (1.5 L) and de-mineralized water (200 ml) was added at 1O0C to 150C. The reaction mixture was stirred for 15 minutes and the layers were separated. Vacuum was applied to the water layer to remove excess tetrahydrofuran at 150C to 2O0C. 6 N hydrochloric acid (40 ml) was added to the reaction mixture at 1O0C to 150C over a 5 minute to 10 minute duration to attain a pH of about 1.4. Enoantichromos carbon (10 g) and Celite (10 g) were added to the reaction mixture and stirred for 20 minutes at 1O0C to 150C. The reaction mixture was filtered through the Celite bed and washed with water (300 ml). N,N-dimethylformamide (100 ml) was added to the filtered solution at 1O0C followed by slow addition of isopropanol (4.5 L) in 4 hours to 5 hours at 50C to 1O0C. The mixture was stirred for 4 hours at O0C to 50C, filtered and washed with isopropanol (500 ml) and ethanol (200 ml) under nitrogen atmosphere. The solid was dried under reduced pressure at 4O0C to 45C to obtain the title compound.Yield: 45.0 g
