Versuchsvorschrift
The same procedures used in Example 1 were repeated except for using 725 mg of indole-4-carbaldehyde and 2-thienylmethyl methanesulfonate instead of the benzyl bromide used in Example 1 to give 392 mg of 1-(2-thienylmethyl)indole-4-carbaldehyde as pale yellow crystals. The yield thereof was found to be 33%.
