Versuchsvorschrift

To a stirred solution of 600 mg. of 6-(triphenylmethylamino)-2,2-dimethyl-3-(1-[2-methoxycarbonylethyl]tetrazol-5-yl)penam (containing ca 4.5% of methanol) in 1 ml. of chloroform, is added a solution of 375.2 mg. of diazabicyclo[4.3.0]non-5-ene in 0.5 ml. of chloroform. Stirring is continued for a further 3 hours, and then the solution is diluted with a further 2 ml. of chloroform. The latter solution is washed quickly with 5 ml. of 2N hydrochloric acid, and then a further 5 ml. of 2N hydrochloric are added. The resulting mixture is cooled to ca 0° C., and the solid which precipitates is filtered off, giving 323 mg. (71% yield) of the title compound. The NMR spectrum (DMSO-d6) of the product shows absorptions at 7.40 ppm (m, 15H), 5.30 ppm (s, 1H), 4.60 ppm (m, 2H), 1.58 ppm (s, 3H) and 0.78 ppm (s, 3H).
