Reaction Steps

850 mg (2.5 millimoles) of Compound 101 was suspended in 5 ml of glacial acetic acid, and 0.26 ml (5.5 millimoles) of hydrazine monohydrate was added to the suspension. The mixture was heated under reflux for 5 hours and the reaction mixture was cooled to room temperature. The precipitate was collected by filtration, and recrystallized from DMF-water to obtain 440 mg (yield 52.4%) of Compound 1.
