実験手順
This compound was prepared following the procedure described in example 13 (part B) starting with 8 g (26.4 mmol) of 4-(5-methoxy-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester (example 87, part B) and 30 mL (30 mmol) of a freshly prepared 1M solution in ethyl ether of 3-bromomethyl-furan. The reaction mixture was stirred at room temperature for 18 hours. After standard work-up, 9.9 g (99% of yield) of 4-(1-furan-3-ylmethyl-5-methoxy-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained.
