실험 절차

3-Phenyl-1,4,5,6-tetrahydropyridazine (2.4 g) synthesized in Reference Example 1 was dissolved in chloroform (50 ml). Thereto were added nicotinic acid chloride hydrochloride (2.6 g) and triethylamine (3.2 g) with ice-cooling. Stirring was conducted for 30 minutes. The reaction mixture was washed with water, dried over anhydrous sodium sulfate and then concentrated. The residue was purified by silica gel column chromatography to obtain 1.8 g of a title compound.
