Versuchsvorschrift

1-Nicotinoyl-3-phenyl-2-pyrazoline (0.1 g) synthesized in Example 3 was dissolved in ethanol (5 ml). Thereto was added 1 N hydrochloric acid-ethanol (0.9 ml) with ice-cooling. The resulting crystals were collected by filtration, washed with ether and dried to obtain 0.1 g of a title compound as yellow crystals.
