Versuchsvorschrift

5-Butyl-1H-indole-2-carbaldehyde was synthesized as in Example 3.1 using 5-bromo-1H-indole-2-carbaldehyde (300 mg, 1.34 mmol) in place of 5-bromo-2-formylfuran and potassium butyltrifluoroborate (352 mg, 2.21 mmol) in place of hexylboronic acid to give 5-butyl-1H-indole-2-carbaldehyde (75 mg, 28%). Used without further characterization.
