Reaction Steps
To 3-(tert-butoxycarbonylamino)-3-(thiophen-3-yl)propyl 4-methylbenzenesulfonate (E73B) in DMSO is added NaCN, and the solution is heated to 90° C. for 2 hours. The reaction is cooled, poured into NaCl (sat), and extracted with EtOAc. The organics are dried (Na2SO4), filtered, and evaporated. Column chromatography (SiO2, 25% EtOAc/Hexanes) gives pure tert-butyl 2-cyano-1-(thiophen-3-yl)ethylcarbamate (E73C).
