Procedure: 2-carboethoxycyclohexanone, finely powdered potassium carbonate, 2-bromomethyl furan, and tetrabutylammonium iodide are reacted by the method of Example 38 to generate the title material.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: This compound was prepared following the procedure described in example 13 (part B) at room temperature for 15 hours, starting with 0.3 g (1.0 mmol) of 4-(5-methoxy-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester and 2.11 mL (1.3 mmol) of a freshly prepared 0.61 M solution of 2-bromomethylfuran in ethyl ether. After standard work-up, 0.38 g (100% of yield) of 4-(1-furan-2-ylmethyl-5-methoxy-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained. This compound was prepared

Procedure: This compound was prepared following the procedure described in example 13 (part B) at room temperature for 15 hours, starting with 0.3 g (1.0 mmol) of 4-(6-fluoro-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester and 2.7 mL (1.6 mmol) of a freshly prepared 0.61 M solution of 2-bromomethylfuran in ethyl ether. After standard work-up, 0.38 g (100% of yield) of 4-(6-fluoro-1-furan-2-ylmethyl-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained. This compound was prepared

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: This compound was prepared following the procedure described in example 13 (part B) starting with 9.4 g (34.4 mmol) of 4-(1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester and 40 mL of (40 mmol) of a freshly prepared 1M solution in ethyl ether of 2-bromomethyl-furan. The reaction mixture was stirred at room temperature for 18 hours. After standard work-up, 13.2 g (100% of yield) of 4-(1-furan-2-ylmethyl-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained. This compound was prepared

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: This compound was obtained following procedure described in example 13 (part B) at room temperature for 5 hours, starting with 5 g (17.2 mmol) of 4-(6-fluoro-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were and 3.2 g (20 mmol) of 2-bromomethyl-furan. After standard work-up, 6.4 g (99% of yield) of 4-(6-fluoro-1-furan-2-ylmethyl-1H-indol-3-yl)-piperidine-1-carboxylic acid ethyl ester were obtained. This compound was obtained
