Reaction Steps

Compound 102 obtained in Example 2, 4.0 g (14.3 millimoles), was suspended in 2.5 ml of glacial acetic acid, and 1.8 ml (34.2 millimoles) of methylhydrazine was added to the suspension. The mixture was heated under reflux for 10 hours. The reaction solution was cooled to room temperature, and the precipitate was collected by filtration and recrystallized from DMF-water to give 2.5 g (yield: 60.1%) of Compound 4.
