实验过程
Into 20 ml of an aqueous solution containing 2% of sodium hydroxide was dissolved 1.9 g of 2-[1-(ethoxyimino)propyl]-5-(4-methanesulfonamidophenyl)-3-hydroxy-2-cyclohexen-1-one and to the solution was added 3 cc of an aqueous solution containing 10% of calcium chloride at room temperature. The water was removed under reduced pressure and the residue was dissolved in ethanol and an insoluble sodium chloride was separated with a filtering step. The ethanol was distilled off under reduced pressure and 1.5 g of white powder having a melting point of 250° C. or more was obtained.
