Procedure:
A mixture of 0.85 g of the product of Step D, 0.8 ml of tert.-butyl bromoacetate and 4 ml of dimethylformamide stood in an ice bath for 5 minutes and then 1.7 g of silver oxide were added thereto. The mixture was stirred for one hour after removal of the bath and the mixture was vacuum filtered. The filter was rinsed with ethyl acetate and 80 ml of water were added to the filtrate which was decanted. The aqueous phase was extracted twice with 20 ml of ethyl acetate and the combined organic phases were washed twice with 50 ml of aqueous sodium chloride solution, dried, treated with 80 mg of activated carbon and vacuum filtered. The filter was rinsed with ethyl acetate and the filtrate was evaporated to dryness under reduced pressure. The residue was taken up in isopropyl ether and after efflorescence, the mixture was vacuum filtered. The product was rinsed with isopropyl ether and dried to obtain 0.724 g of the syn isomer of diphenylmethyl 7-[2-(2-tritylamino-4-thiazolyl)-2-(tert.-butoxycarbonylmethyloxyimino)-acetamido]-3-acetoxymethyl-ceph-3-eme-4-carboxylate with Rf=0.34 (methylene chloride containing 5% of ether).

Procedure:
224 mg of 4-[N(4-methoxyphenyl)amino]benzonitrile was dissolved in 1.2 ml of N,N-dimethylformamide, and 48 mg of sodium borohydride was added thereto under cooling with ice, followed by stirring at room temperature for 30 minutes. The previously prepared 4-(t-butyldimethylsilyloxy)benzyl chloride was dissolved in 1.2 ml of N,N- dimethylformamide and added to the reaction mixture under cooling with ice, followed by stirring at room temperature for 2 days. After water was added to the reaction mixture, the product was extracted with ethyl acetate. After the extract was washed with water and dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The resulting residue was dissolved in 1.2 ml of tetrahydrofuran, and 1.2 ml of a 1 M tetrahydrofuran solution of tetrabutylammonium fluoride was added thereto, followed by stirring at room temperature for 15 minutes. After a saturated aqueous solution of sodium hydrogen carbonate was added to the reaction mixture, the product was extracted with ethyl acetate. After the extract was washed with water and dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The resulting crude product was purified by silica gel column chromatography (using ethyl acetate as the eluent) to obtain 229 mg of 4-[N-(4-hydroxybenzyl)-N-(4-methoxyphenyl)amino]benzonitrile.

A solution of 1.07 g (4.4 mmol) of 5,6-difluoro-2-methyl-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid methyl ester (Example 32) in 25 mL of dichloromethane is cooled to −20° C. and treated dropwise with 0.85 g (6.0 mmol) of chlorosulfonyl isocyanate. The reaction is stirred at −20° C. for 1 hour, treated with 1.0 g (12 mmol) of solid sodium acetate, and the solvent is removed in vacuo. The residue is cooled in an ice bath and triturated with a saturated solution of sodium acetate in brine. The precipitate is removed by filtration, washed with the sodium acetate solution and dried in vacuo. The dried precipitate is washed with ether to remove starting material and dried in vacuo. The dried solid is suspended in 40 mL of dry tetrahydrofuran, cooled to 5° C. and treated portionwise with 1.2 g (12 mmol) of sodium tert-butoxide. After the addition is complete, the reaction mixture is stirred at 5° C. for 30 minutes, the bath is removed, and the reaction is stirred to room temperature over 1 hour. The solvent is removed in vacuo; the residue is dissolved in water, cooled to 5° C. and acidified with formic acid. The resulting precipitate is removed by filtration, washed with water and dried in vacuo affording 0.8 g of the title compound, mp 212–214° C.
