Participants

Reaction Steps

Ten vials were each charged with 3-oxo-3-(3-bromophenyl)propionitrile (1.0 g, 4.5 mmol), hydrazine (0.2 mL) and EtOH (1 mL), and subject to microwave irradiation at 120° C. for 60 min. The contents of all vials was pooled and the solvent was evaporated in vacuo. The crude product was dissolved in ethanol (approx. 200 mL) and acidified by the addition of 4N HLC in dioxane, after 0.5 h the precipitate was collected, washed with additional ethanol and dried to yield 9.60 g. LC/MS (10% MeOH, 90% H2O, 0.2% H3PO4 to 90% MeOH, 10% H2O, 0.2% H3PO4, 2 minute gradient with an Exterra C18 S-5 column 4.6×30 mm): [M+H]+ m/z=239.0, 241.0; retention time=0.85 min.
