Reaction Steps

To a stirred solution of t-BuOK (1 g, 8.9 mmol) in DMSO (15 mL) at rt, was added compound cyanoacetamide (0.824 g, 9.8 mmol) and (E)-hept-3-en-2-one (1 g, 8.91 mmol). Reaction mixture was stirred for 30 min at rt. Additional t-BuOK (3 g, 26.7 mmol) was added and reaction was stirred at rt in presence of air. On completion, it was diluted with H2O and slowly by 4N HCl. Precipitated solid was filtered, washed with water and dried. Crude product was triturated with ether to afford the title compound (0.5 g, 33%).
