Procedure

To a stirred solution of compound 38 (2.3 g, 10.80 mmol) in DCM (90 mL) were added successively 2-aminoindane (1.4 mL, 10.80 mmol), Na(OAC)3BH (6.86 g, 32.39 mmol) and acetic acid (2 mL) at 0° C. The resulting mixture was allowed to stir at rt for 16 hours. The reaction mixture was diluted in DCM and washed with 1N NaOH, water and brine solution. The organic layer was dried over anhydrous Na2SO4, filtered and evaporated. The crude material was purified by Combiflash® chromatography eluting with 3-4% of methanol-DCM to provide compound 39.
