실험 절차

32.2 g (0.2M) dry indol-4-yl carboxylic acid are suspended in 150 ml absolute methylene chloride. 26 ml (0.3M) oxalyl chloride are added to the stirred mixture at 20° over 30 minutes. Gas evolution results. The mixture is stirred for 31/2 hours at 20° C. 150 ml Hexane are added. The mixture is stirred for another 20 minutes and the resultant heading compound filtered off, washed with methylene chloride/hexane 1:1 dried at 20° in a vacuum to give beige crystals, which are used further without purification.
