Procedure:
In a nitrogen atmosphere, 4-(4-chlorophenyl)-2-ethyl-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine (1 g) was dissolved in diethyl carbonate (35 ml) and 60% sodium hydride was added thereto at room temperature with stirring. After refluxing under heating for 2 hours, the reaction mixture was cooled to room temperature and ethyl bromoacetate (0.32 ml) was added thereto. After stirring at room temperature for 3 hours, the reaction mixture was poured into cold water and extraceted with ethyl acetate. The extract was washed with water, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography and the objective fraction was concentrated under reduced pressure. The residue concentrated was suspended in a mixture of ethanol (90 ml) and water (30 ml). To the suspension was added barium hydroxide 8 hydrate (0.65 g) at room temperature with stirring and the mixture was stirred at room temperature for 10 hours. The reaction mixture was concentrated under reduced pressure and water was added to the residue. The mixture was washed with ethyl acetate. The aqueous layer was adjusted to pH 2 with 6N hydrochloric acid and allowed to stand at room temperature overnight. The reaction mixture was neutralized with sodium hydrogencarbonate and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure and isopropyl ether was added for crystallization. As a result, 0.15 g of (4-(4-chlorophenyl)-2-ethyl-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl)acetic acid (0.15 g) was obtained as pale brown crystals, melting point 198°-202° C.

Procedure:
A mixture of 4.58 g of the product of Example 16 and 30 ml of 50% aqueous formic acid was heated at 55° C. for 20 minutes and crystallization occured. The mixture was cooled and was diluted and stirred. The mixture was vacuum filtered and the product was rinsed and dried to obtain 1.257 g of triphenyl carbinol. The filtrate was evaporated to dryness under reduced pressure and the residue was taken up in water. Crystallization occured and the mixture was stirred for 30 minutes and was vacuum filtered. The solid was rinsed and dried to obtain 1.68 g of raw product. The latter was dissolved in 4 ml of a molar solution of sodium bicarbonate and the insolubles were ground up. The mixture was vacuum filtered and the filtrate was rinsed with water. 0.24 ml of acetic acid were added to the filtrate and the mixture was vacuum filtered. The precipitate was rinsed with water and dried to obtain 426 mg of purified product. 0.15 ml of formic acid were added to the filtrate and crystallization occurred. The mixture was vacuum filtered and the product was rinsed with water and dried to obtain 505 mg of more pure anti isomer of 3-acetylthiomethyl-7-[{2-(2-amino-4-thiazolyl)-2-methoxyiminoacetyl}amino]-ceph-3-eme-4-carboxylic acid melting at 190° C.
