Reaction Steps
To 91 mg of 2-[N-(p-chlorobenzyl)-3-(t-butylthio)-5-(quinolin-2-ylmethoxy)indol-2-yl]ethanol from Step B in 2 mL THF at 0° C. under an argon atmosphere was added 40 mg of 80% sodium hydride over 30 min. Ethyl bromoacetate (0.3 ml) was added to the solution and the reaction stirred at RT overnight. The reaction was poured onto 10 mL of NH4OAc (25% solution), extracted with 3×10 mL of EtOAc, washed with 20 mL of H2O and dried over MgSO4. Removal of the solvent followed by column chromatography on silica gel afforded the ethyl ester of title compound. Hydrolysis of this ester under the conditions described in Step B of Example 1 provided the title compound, m.p. 185° C. (dec.).
