Reaction Steps

(S)-tert-butyl(1-(5-bromo-4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)ethyl)carbamate (500 mg, 1.13 mmol), zinc cyanide (166 mg, 1.41 mmol), and tetrakis(triphenylphosphine)Pd(0) (124 mg, 0.11 mmol) were combined in NMP (5 mL). The mixture was degassed under Ar and heated to 90° C. overnight. The reaction was poured into EtOAc, washed with water (3×), and purified by flash chromatography (40 g silica, 0-50% EtOAc/hexanes) to give (S)-tert-butyl(1-(5-cyano-4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)ethyl)carbamate as a white solid. ES/MS 391.2 (M+H+).
