Reaction Steps

In argon atmosphere, potassium cyanide (260 mg, 4 mmol) and 2-oxo-bicyclo [3.1.0] hexane-1-carboxylic acid methyl ester (462 mg, 3 mmol) were added to hexamethylphosphoric triamide (3 ml). The mixture was stirred at the room temperature for 24 hours and was treated in accordance with the process of Preparation 4 to obtain 300 mg of 5-cyanomethyl-2-oxo-cyclopentanecarboxylic acid methyl ester. Yield: 55%.
