2-O-(2,5-dioxopyrrolidin-1-yl) 1-O-methyl benzene-1,2-dicarboxylate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of (S)-2-amino-2-phenylethanol (3 g, 21.87 mmol) in water (26.5 mL), and acetonitrile (46.4 mL) was added 2,5-dioxopyrrolidin-1-yl methyl phthalate (5.76 g, 20.78 mmol) at room temperature. The reaction mixture was stirred at room temperature for overnight. After acetonitrile was removed in vacuo, the reaction mixture was then extracted with EtOAc. The organic was washed by water and brine, dried over anhydrous sodium sulfate, filtered off, and concentrated in vacuo yielding (S)-2-(2-hydroxy-1-phenylethyl)isoindoline-1,3-dione (2.2 g, 40%). LCMS (m/z): 268 (MH+), 0.79 min. After acetonitrile was removed in vacuo the reaction mixture was then extracted with EtOAc The organic was washed by water and brine dried over anhydrous sodium sulfate filtered off concentrated in vacuo
