实验步骤: To a solution of 2-[(1S)-2-hydroxy-1-methyl-ethyl]isoindoline-1,3-dione (47 g, 229 mmol) and iodoethane (89.3 g, 572.5 mmol) in THF (376 mL) is added potassium tert-butoxide (64.25 g, 572.5 mmol) in one portion. The mixture is stirred under a nitrogen atmosphere for 15 h. The mixture is diluted with ethyl acetate (200 mL) and washed with brine (200 mL). The aqueous phase is extracted with ethyl acetate (2×100 mL). The combined organic extracts are dried over MgSO4, filtered, concentrated under reduced pressure, and then dried under high vacuum to afford the title compound (39.4 g, 74%) as an orange solid that is used without further purification. LC-ES/MS m/z 234 (M+1). washed with brine (200 mL) The aqueous phase is extracted with ethyl acetate (2×100 mL) The combined organic extracts are dried over MgSO4 filtered concentrated under reduced pressure dried under high vacuum

实验步骤: A mixture of (2S)-2-aminopropan-1-ol (26 mL, 333 mmol) and phthalic anhydride (51.7 g, 349.4 mmol) is heated at 140° C. overnight. During this time the solid becomes an orange liquid. The reaction is cooled to RT and diluted with ethyl acetate (10 mL/g). The organic phase is washed with saturated NaHCO3 and 10% citric acid, dried over MgSO4, filtered, and concentrated to afford the title compound (68.3 g, 98%) as a white solid that is used without further purification. LC-ES/MS m/z 206 (M+1). The reaction is cooled to RT The organic phase is washed with saturated NaHCO3 and 10% citric acid dried over MgSO4 filtered concentrated
