Reaction Steps

A solution of 1.33 g (33 mmol) of sodium hydroxide in 120 mL of water was added to a suspension of 6.31 g (16.6 mmol) of 2-{2-[4-(1H-indol-3-yl)-piperidin-1-yl]-ethoxy}-benzoic acid methyl ester (prepared in Example 1, part D) in 120 mL of ethanol. This mixture was heated at 60° C. for 3 hours and the solvent was removed under reduced pressure. After addition of 50 mL of water, the crude mixture was neutralised with HCl 2N and the solid formed was isolated. After recrystallisation from acetonitrile, 2.6 g (43% of yield) of a white solid corresponding to the desired product were obtained.
