Procedure
A solution of 0.812 g of the product of Step A, 4 ml of acetone and 1 ml of N hydrochloric acid was stirred at room temperature for 3 hours and 1 ml of an aqueous solution of 1M sodium bicarbonate, 10 ml of water and 5 ml of ethyl acetate were added thereto to obtain 0.551 g of the syn isomer of tert.-butyl 7-[2-(2-tritylamino-4-thiazolyl)-2-hydroxyimino-acetamido]-3-acetoxymethyl-ceph-3-eme-4-carboxylate melting at ≃200° C.
