Procedure

To a stirred solution of 2-indanone (5 g, 37.83 mmol) in DCM (135 mL) were successively added aniline (3.4 mL, 37.83 mmol), AcOH (2.16 mL, 37.83 mmol) and Na(OAc)3BH (11.22 g, 52.96 mmol) portion-wise at ice cold conditions. The reaction mixture was stirred at rt for 16 hours. The reaction mixture was then diluted with EtOAc (450 mL) and washed with water (150 mL) and brine (50 mL). The organic layer was dried over Na2SO4, filtered and concentrated. The crude material was purified by Combiflash® chromatography and eluted with 1.7% EtOAc in hexane to obtain compound 7.
