Versuchsvorschrift

A solution of 8.0 g of ethyl 3-(3-indolyl)propionate and 6.3 g of 3-bromopyridine in 100 ml of pyridine is refluxed with 5.0 g of copper oxide and 10 g of anhydrous potassium carbonate for 48 hours. Evaporation and chromatography on 300 g of silica with 1:1 ethyl ether:hexane as eluant yields 3-[2-(ethoxycarbonyl)ethyl]-N-(3-pyridyl)indole as an oil; Rf =0.2, IR (CH2Cl2) 1725 cm-1.

Aufarbeitung

  1. customEvaporation and chromatography on 300 g of silica with 1:1 ethyl ether
