Participants

Reaction Steps

The substance [28] (191 g, 0.393 M) was dissolved in DMF (500 ml). Hydrazine hydrate (100%) (200 ml) was added dropwise and stirred at room temperature for three hours. The DMF was removed in vacuo and water was added thereto. The thus-formed precipitate was filtered, dried, and recrystallized twice from ethyl acetate-hexane to obtain the substance [29] (183.6 g, yield: 96.0%).
