2-Bromo-1,2-diphenylethan-1-one → HCID 9552908, compound

Participants

Reaction Steps

A solution of desyl bromide (1.72 g, 6.26 mmol), and 2-[(E)-1-(4-methoxyphenyl) methylidene]-1-hydrazinecarboximidamide (2.4 g, 12.5 mmol) was heated at reflux in ethanol (10 mL) for 2 h. The mixture was cooled at room temperature for additional 10 h, and a yellow precipitate formed. The yellow precipitate was filtered, washed with hot water and recrystallized from ethanol to give N1-[(E)-1-(4-methoxyphenyl)methylidene]-4,5-diphenyl-1H-1,2-imidazolediamine 3 (1.57 g, 68%) as a yellow solid.
