Hydrazine → HCID 9929207, compound

Participants

Reaction Steps

Anhydrous hydrazine (0.10 g) was added to a solution of 3-Dimethylamino-1-[4-(5H,11H-pyrrolo[2,1-c][1,4]benzodiazepine-10-carbonyl)-phenyl]-2-buten-1-one (0.50 g) in glacial acetic acid (25 ml). The reaction mixture was refluxed for 18 hours and then concentrated under vacuum. The solid was extracted with dichloromethane and washed with saturated aqueous sodium bicarbonate solution. The dichloromethane solution was dried over anhydrous sodium sulfate and filtered through a short column of hydrous sodium magnesium silicate and further eluted with several volumes of dichloromethane. The combined organic phase was concentrated on a steam bath with the gradual addition of hexane to give an opaque solution. After cooling the amorphous solid was recovered by filtration to yield the product (0.33 g), MS, m/z: 368 (M)+.
