Participants

Reaction Steps

(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-heptane (70 mL) respectively, and heated to reflux. Lithium bromide (0.15 g, 1.74 mmol) was added, the mixture was reacted for 4 h, white solid was obtained by filtration (6.53 g, yield: 89.5%).
