Reaction Steps

To a 50 mL round-bottomed flask was added n-(2-bromoethyl)phthalimide, 95% (508 mg, 1999 μmol, Aldrich), 4-fluoroaniline (193 μL, 1999 μmol, Aldrich), DMF (2 mL), sodium carbonate (336 mg, 3999 μmol). The reaction mixture was stirred at 80° C. for overnight. The reaction mixture was diluted with water (20 mL) and extracted with EtOAc (2×40 mL). The organic extract was washed with water (20 mL), saturated NaCl (20 mL), dried over Na2SO4, filtered and concentrated in vacuo and the residue was purified by silica gel chromatography, eluting with 30% EtOAc/hexanes to give 2-(2-(4-fluorophenylamino)ethyl)iso-indoline-1,3-dione. MS (ESI pos. ion) m/z: 285 (M+1).
