Reaction Steps

The title compound was prepared by the route outlined in Scheme 11 and using the experimental from Example 37, Step 3, with intermediate 5-(tert-butyl-dimethyl-silanyloxy)-indole-1-carboxylic acid tert-butyl ester (11a) (2.90 g, 8.3 mmol) and (6a), 3-iodo-5-nitro-1-(2-trimethylsilanyl-ethoxymethyl)-1H-pyridin-2-one (3 g, 7.6 mmol). The resultant crude product was purified by flash chromatography on SiO2 with hexane—20% ethyl acetate/hexane (gradient) to afford after trituration using hexane, the title compound as a pale yellow solid, 3.67 g, 79%.
