Procedure

A mixture of 21 g of the product of Step A, 80 ml of acetone and 27 ml of 2 N hydrochloric acid was stirred at room temperature for 90 minutes and 55 ml of water were added thereto with stirring. The acetone was evaporated under reduced pressure and 140 ml of ethyl acetate were added with stirring. The decanted aqueous phase was extracted with ethyl acetate and the combined organic phases were washed with half saturated aqueous sodium chloride solution, was dried and vacuum filtered to obtain the syn isomer of 3-methyl-7-[2-(2-tritylamino-4-thiazolyl)-2-hydroxyiminoacetamido]-ceph-3-eme-4-carboxylic acid.
