Versuchsvorschrift

Diethyl cyanomethylphosphonate (0.19 ml, 1.175 mmol) was dissolved in THF (7 ml). The solution was cooled to 0° C. Sodium hydride (0.0818 g, 2.045 mmol) was added to the reaction. The reaction was allowed to stir for several minutes. Tert-butyl [2-{[4-(bromomethyl)benzoyl]amino}-4-(2-thienyl)phenyl]carbamate (0.5047 g, 1.035 mmol) was added in a solution of THF. The reaction was allowed to slowly warm to room temperature and stir overnight. The reaction was diluted with ethyl acetate and quenched with saturated aqueous ammonium chloride. The aqueous layer was extracted with ethyl acetate three times. The combined organic layer was dried over sodium sulfate, filtered, and concentrated. The resulting residue was partially purified by column chromatography on silica gel. MS: cal'd 484 (MH+-Boc), exp 484 (MH+-Boc).
