To a solution of (E)-6-(2-(tert-butoxycarbonylamino)phenylamino)-6-oxohex-4-enyl methanesulfonate (1) (200 mg, 0.5 mmol) in DMF was added potassium 1,3-dioxoisoindolin-2-ide (111 mg, 0.6 mmol), the mixture was stirred at RT for 12 hours. The mixture was poured into 100 mL water, then extracted with MTBE (25 mL×2), and the organic layers were washed with water (25 mL×3) and brine (3×20 mL), dried over Na2SO4 and concentrated to give the desired compound of (E)-tert-butyl 2-(6-(1,3-dioxoisoindolin-2-yl)hex-2-enamido)phenylcarbamate (3) (135 mg, yield 60%) as a yellow oil after purification by column chromatography on silica gel (eluent: PE:EA=1:1). LC-MC found 450 (M+H)+.
