Versuchsvorschrift

The same procedures used in Example 1 were repeated except for using 435 mg of indole-4-carbaldehyde and 680 mg of 2-(thien-2-yl)ethyl methanesulfonate instead of the benzyl bromide used in Example 1 to give 299 mg of 1-[2-(thien-2-yl)ethyl]indole-4-carbaldehyde as an orange-colored oily substance. The yield thereof was found to be 39%.
