Participants

Conditions

Temperature: 140 °C

Procedure

(S)-2-(oxiran-2-ylmethyl)isoindoline-1,3-dione (3.87 g, 19.06 mmol, 1.1 eq.) and 4-(4-isocyanatophenyl)morpholin-3-one (3.77 g, 17.29 mmol) were dissolved in N,N-dimethylformamide (70 mL) respectively and heated to 140° C. Then lithium bromide (0.15 g, 1.74 mmol) was added, the mixture was reacted for 4 h, white solid was obtained by filtration (6.68 g, yield: 91.75%).
