실험 절차

To a cooled (0° C.) solution of 3-(2-fluoro-4-trimethylsilanyl-phenylamino)-1-(2-triisopropylsilanyloxy-ethyl)-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid methyl ester (1.78 g, 3.20 mmol) in DCM (35 mL) was added iodine monochloride (1M in DCM, 6.40 mL) dropwise over 10 minutes. The mixture was stirred for 1 hour then quenched by the addition of saturated sodium thiosulphate solution. The solution was partitioned between ethyl acetate and an saturated solution of sodium hydrogencarbonate. The organic layer was separated, washed with water then brine, dried (Na2SO4), filtered and evaporated to give a residue. The residue was purified by flash chromatography (Si-PPC, cyclohexane:ethylacetate, gradient 100:0 to 0:100) to provide the title compound as a yellow oil (1.52 g, 79%). LCMS (method B): RT=3.47 min, M+H+=612.
