Reaction Steps

N-Chlorosuccinimide (1.6 g, 11.96 mmol) was added to a solution of intermediate D5 (2.0 g, 11.96 mmol) in DMF (30 ml). The reaction was stirred at room temperature overnight and then it was concentrated in vacuo. The crude product was purified by column chromatography (silica gel; 0-5% methanol/DCM as eluent) to yield intermediate D8 (2.0 g, 83%).
