Reaction Steps
Following a published procedure (Tetrahedron, 2002, 5251) 6-bromo-9H-pyrido[3,4-b]indole-3-carbaldehyde (40 mg, 0.145 mmol), hydrazine hydrate (51 mg, 1.02 mmol) and KOH (29 mg, 0.509 mmol) were combined in 0.5 mL of ethylene glycol and heated to 150° C. overnight. The reaction was cooled to room temperature. Ice chips were added and the mixture was stirred in an ice bath for 1 hour. White precipitate formed which was filtered and dried to afford the desired compound in 73% yield.
