Procedure

(S)-2-(oxiran-2-ylmethyl)isoindoline-1,3-dione (3.69 g, 18.14 mmol, 1.05 eq.) and 4-(4-isocyanatophenyl)morpholin-3-one (3.77 g, 17.29 mmol) were dissolved in butyl acetate (70 mL) respectively, heated to 120° C. Then a solution of magnesium iodide in diethyl ether (0.3 mmol, 0.3 mL) was added, the mixture was reacted for 4 h, white solid was obtained by filtration (6.88 g yield: 94.50%).
