Sodium bis(trimethylsilyl) amide (2 mL, 2 M in THF, 2 mmol) was added dropwise at 0° C. to a solution of 5-chloro-2,3-dihydro-isoindol-1-one (0.34 g, 2 mmol) in THF (10 mL). After stirring for 10 min, 1-bromomethyl-4-methoxy-benzene (0.52 g, 2.6 mmol) was added dropwise. The resulting reaction mixture was allowed to stir at room temperature for 48 hours before quenching with saturated aqueous ammonium chloride solution. After extraction with EtOAc, the organic layer was washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give the crude product (0.6 g, 100%) as a yellow oil. MS: 288.0 (M+H+). It was used directly in the next step, without further purification.
