Versuchsvorschrift

A thick walled tube was charged with 1H-pyrrole-2-carbaldehyde (2.0 g, 21.0 mmol), 2-methylphenylacetonitrile (2.5 g, 18.9 mmol, 0.9 equivalents), ethanol (75 ml), and 40% aqueous Triton B (4.0 ml, 3.3 mmol). The tube was sealed and heated to 90° C. for 4 days. Removal of the solvent, followed by chromatography on silica gel using dichloromethane/petroleum spirits (20:80) as eluant afforded a yellow solid (1.2 g). This is Compound 16 in Table 8.
