Reaction Steps
To a solution of ethyl (2E/Z))-(5-bromo-2,3-dihydro-1H-inden-1-ylidene)(cyano)ethanoate (Prep1, 3.1 g, 10.15 mmol) in ethanol (23 mL) a solution of KCN (1.65 g, 2.5 eq) in water (6 mL) was added and the reaction mixture was warmed to 65° C. and stirred for ˜16-24 h. Then the solvent was removed under reduced pressure, the crude was treated with ether and water. Crystallization from ethanol gave the title compound (1.87 g, y=70%).
