Participants

Reaction Steps

Compound 102 in an amount of 1.2 g (4.3 millimoles) was suspended in 10 ml of glacial acetic acid, and 0.46 ml (9.4 millimoles) of hydrazine monohydrate was added to the suspension. Thereafter, the mixture was heated under reflux for 3 hours. The reaction solution was cooled to room temperature, and the precipitate was collected by filtration and recrystallized from DMF-water to give 530 mg (yield: 44.3%) of Compound 2.
