Reaction Steps
CDP-12 was prepared similar to the method used to prepare CDP-2 from potassium salt of 3-oxo-2-cyanopropanoic acid ethyl ester (1.43 g, 8 mmol) and tetramethylenebis(triphenylphosphonium bromide) (2.96 g, 4 mmol) to give the corresponding product in quantitative yield that is hygroscopic.
