To a solution of 3-[1-(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)-1H-indol-3-yl]propyl methanesulfonate (Intermediate 42; 3.5 g, 8.5 mmol) in ketone (20 mL) was added sodium iodide (2.55 g, 17 mmol). The reaction mixture was stirred overnight at 50° C. The crude reaction was filtered and the solvent was removed under reduced pressure. The crude obtained was purified over silica gel eluting with hexane:ether (100/0 to 0/100) to obtain the title compound (2.7 g, 71%).
