The mixture was stirred at room temperature for 45 minutes. After cooling the mixture to 5\u00b0 C. again, pyrazole-4-carbaldehyde (255.4 mg, 2.66 mmol) was added dropwise to the mixture while stirring and stirred at room temperature overnight. Zinc acetate in the mixture was filtered off and the filtrate was concentrated and purified by silica gel chromatography (chloroform\/methanol=10\/1).
