Reaction Steps
1.12 g of isoindoline are added to 3.5 g of 5-(1-ethoxycarbonylbutyl)-1-tertbutoxycarbonyl-2,3-dioxoindoline in 50 ml of tetrahydrofuran, and the mixture is subsequently stirred at 23° C. for 1 h. The mixture is evaporated to dryness in vacuo and purified by column chromatography, giving 1.4 g (30%) of ethyl 2-[4-(tert-butoxycarbonylamino)-3-(2-isoindolin-2-yl-2-oxoacetyl)phenyl]-pentanoate; LC-MS retention time: 2.78 min (“nonpolar” gradient).
