This compound was prepared following the procedure described in example 13 (part B) starting with 9.1 g (30 mmol) of 4-(5-methoxy-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester (example 87, part B) and 50 mL (50 mmol) of a freshly prepared 1M solution in ethyl ether of 2-bromomethyl-thiophene. The reaction mixture was stirred at room temperature for 18 hours. After standard work-up, 7.7 g (65% of yield) of 4-(5-methoxy-1-thiophen-2-ylmethyl-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained.
