Procedure
600 mg of Compound 23 was dissolved in 75 ml of a mixed solvent of dimethylformamide and methanol (1:1), 0.613 ml of hydrazine monohydrate was added and the mixture was stirred at 50° to 60° C. for 1.5 hours. Additional 0.307 ml of hydrazine monohydrate was added and the mixture was stirred at 50° to 60° C. for 10 minutes. The reaction solution was concentrated under reduced pressure, the residue was subjected to silica gel column chromatography (chloroform:methanol:aqueous ammonia =9:1:1) to give Compound 24 which was dissolved in ethanol, a 5.5N hydrochloric acid-isopropylalcohol solution was added, and the precipitated crystals were collected by filtration to give 331 mg (69%) of Compound 24.
