실험 절차
To a mixture of 6-aminopyridazine-3-carboxylic acid (1-1) (1.39 g, 10 mmol) in ethanol in a sealed flask was added 2-chloroacetaldehyde (4 mL, 40% aqueous). The reaction mixture was stirred at room temperature for 5 min, then heated at 100° C. overnight. After cooled to room temperature, the mixture was concentrated to afford the title compound (1.63 g). MS (m/z): 164 (M+1)+
