Reaction Steps

To 2-(tert-butoxycarbonylamino)-2-(thiophen-3-yl)ethyl 4-methylbenzenesulfonate (E2) in DMSO was added NaCN, and the solution was heated to 90° C. for 2 hours. The reaction was cooled, poured into NaCl (sat), and extracted with EtOAc. The organics were dried (Na2SO4), filtered, and evaporated. Column chromatography (SiO2, 25% EtOAc/Hexanes) gave pure tert-butyl 2-cyano-1-(thiophen-3-yl)ethylcarbamate (E3).
