Conditions

Temperature: 120 °C

Procedure

(S)-2-(oxiran-2-ylmethyl)isoindoline-1,3-dione (4.04 g, 19.87 mmol, 1.15 eq.) and 4-(4-isocyanatophenyl)morpholin-3-one (3.77 g, 17.29 mmol) were dissolved in 1,4-dioxane (70 mL) respectively, then heated to 120° C. and magnesium bromide (0.22 g, 1.21 mmol) was added. The mixture was reacted for 4 h, white solid was obtained by filtration (6.94 g, yield: 95.1%).
