To a stirred suspension of 118 (2.00g, 24.O7mmol) in concentrated HC1 (32mL) was added a solution ofNaNO2 (3.32g. 48.i4mmoi) in water (5mL) over 5 minutes at 0C. To the resulting orange reaction mixture was added a solution of KI (9.99g, 60 iSmmol) in water (l0mL) over 10 minutes. The reaction mixture was stirred at 0C for 30 minutes and then kept at 28C for another 2 hours, TLC showed the reaction was complete, then, solvent THF (3OmL) was added,followed by water (3OmL). The aqueous mixture was extracted with EtOAc (3 x8OmL) and the combined organic extracts were washed with Na2S2O3 (2 x4OmL), dried over Na2SO4, filtered and concentrated in vacuum to afford product 180 (200 g, crude), the crude product was used directly for the next step without purification.LCMS: m/z, i94.9M+H)??.
