실험 절차

In the same manner as described in Reference Example 2 (1) except that 1-allylpyrrole-2-carbaldehyde (prepared in the same manner as described in Can. J. Chem., 55, 4112, 1977, b.p. 80°-83° C./7 mmHg) (8.1 g, 60 mmole) is used instead of 1-isopropylpyrrole-2-carbaldehyde and further the product is isolated by silica gel column chromatography (solvent, cyclohexane:dichloromethane=3:1) instead of distillation under reduced pressure, there is obtained 1-allylpyrrole-2-carbonitrile (4.0 g, yield: 50%).
