Reaction Steps

2-(1-(2-hydroxyethyl)-2,6-dioxopiperidin-3-yl)isoindolin-1,3-dione (S)-2-(tert-butoxycarbonylamino)-3-phenylpropanoate (100 mg) was dissolved in 25% TFA/DCM (10 mL) and stirred on a magnetic stirrer at room temperature. The mixture was allowed to react for 4 hrs. DCM and most of TFA were removed by rotary evaporation in vacuo. The foam obtained was dissolved in DCM (50 mL). The mixture was washed with saturated sodium bicarbonate and brine, dried over anhydrous magnesium sulfate, and filtered. 52 mg of a solid was obtained after drying in vacuo. 1H NMR (CDCl3, ppm) δ 7.80-7.90 (m, 2H), 7.70-7.80 (m, 2H), 7.10-7.35 (m, 5H), 4.95-5.12 (m, 1H), 4.35-4.45 (m, 1H), 4.15-4.25 (m, 2H), 4.00-4.15 (m, 1H), 3.65-3.72 (m, 1H), 2.95-3.10 (m, 2H), 2.75-2.90 (m, 3H), 2.12-2.20 (m, 1H).
