実験手順

The mixture of 2-(4-pyridylmethyl)-imidazoline (6.6 g, 0.04M) and Raney-Nickle (3 g) was heated initially at 210° C. and gradually raised to 250° C. in 15 min. After the reaction, the reaction was dissolved in ethanol (50 ml) and filtered to remove the catalyst. The filtrate was stripped to dryness and distilled (0.25 mmHg, 180° C.) to give 2-(4-pyridylmethyl)-imidazole (4.1 g, 62% yield).
