Procedure

To a stirred solution of compound 23 (820 mg, 3.55 mmol) in DCM (15 mL) was added 2-amino-indane (472 mg, 3.55 mmol) drop-wise at ice cold conditions. Acetic acid (0.2 mL) was added to the reaction mixture, followed by sodium triacetoxy borohydride (2.2 g, 10.65 mmol) portion-wise at ice cold conditions. The reaction mixture was stirred at rt for 16 hours. The reaction mixture was diluted with DCM, washed with saturated NaHCO3 solution and brine. The organic layer was dried over Na2SO4, filtered and concentrated. The crude material was purified by 230-400 silica gel column chromatography using 1-3% MeOH-DCM as eluent to yield compound 24.
