Procedure
This compound was prepared following the procedure described in example 13 (part D), starting with 4.35 mmol (15 mmol) of 3-piperidin-4-yl-1-thiophen-2-ylmethyl-1H-indole and 4.58 g (20 mmol) of 3-bromomethyl-benzoic acid methyl ester. After the standard work-up, 3.3 g of the corresponding acid was obtained. The crude mixture was purified by flash chromatography over silica gel affording 0.64 g (10% of yield) of the pure acid.
