Procedure

4.78 g of Compound 15 was dissolved in 200 ml of a mixed solvent of dimethylformamide and methanol (1:1), 5.07 ml of hydrazine monohydrate was added and the mixture was stirred at 50-60° C. for 1 hour. 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 16 which was dissolved in ethanol, a 5.5N hydrochloric acid- isopropylalcohol solution was added, isopropyl ether was added, and the precipitated crystals were collected by filtration to give 2.69 g (64%) of hydrochloride of Compound 16.
