Reaktionsschritte

This compound was prepared following the procedure described in example 13 (part B) starting with 2.2 g (7.5 mmol) of 4-(6-fluoro-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester (example 24, part A) and 1.1 mL (8.8 mmol) of 2-chloro-5-chloromethyl-thiophene. The reaction mixture was stirred at room temperature for 18 hours. After standard work-up, 2.2 g (68% of yield) of 4-[1-(5-chloro-thiophen-2-ylmethyl)-6-fluoro-1H-indol-3-yl]-piperidine-1-carboxylic acid ethyl ester were obtained.
