Reaction Steps
To a mixture of the compound (152 mg) obtained in Example 179, methanol (10 ml) and chloroform (10 ml), hydrazine monohydrate (0.05 ml) was added and heated under reflux for 24 h. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure; following addition of 2 N HCl, the mixture was washed with ethyl acetate. Then, the aqueous layer was made alkaline with a 2 N aqueous sodium hydroxide solution and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried with anhydrous sodium sulfate and concentrated under reduced pressure to give 71 mg of the titled compound (yield, 78%).
