Procedure

120 mg of the compound prepared in (11) above was dissolved in a mixed solvent of 7 ml of chloroform and 5 ml of methanol. After the addition of 0.7 ml of hydrazine monohydrate, the mixture was heated under reflux for 1 hour. The reaction mixture was concentrated to dryness and to the residue was added 7 ml of 4N hydrochloric acid, and the mixture was heated under reflux for 1 hour. After concentration to dryness, 10 ml of water to the residue to remove the insoluble substances by filtration. The filtrate was purified in the same manner as in Example 7 to obtain 32 mg of Isomer A and 20 mg of Isomer B of the title compound.
