Reaction Steps

This compound was prepared following the procedure described in example 13 (part B) starting with 4 g (13.8 mmol) of 4-(6-fluoro-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester (example 24, part A) and 3.3 g (16 mmol) of 2-thiophen-3-yl-ethyl methansulfonate. The reaction mixture was stirred at 60° C. for 3 hours. After standard work-up, 5.6 g (100% of yield) of 4-[6-fluoro-1-(2-thiophen-3-yl-ethyl)-1H-indol-3-yl]-piperidine-1-carboxylic acid ethyl ester were obtained.
