実験手順
Hydrochloric acid (40 mL of 1 M) was added to a solution of N-[1-(5-diethoxymethyl-2-methyl-2H-pyrazol-3-yl)-1,1-dimethylethyl]benzamide (8.7 g, 24 mmol) in tetrahydrofuran (40 mL), and the reaction was stirred for ten minutes. tert-Butyl methyl ether and 2 M aqueous sodium carbonate (20 mL) were added. The aqueous layer was extracted twice with tert-butyl methyl ether, and the combined organic fractions were dried over magnesium sulfate and filtered. Hexane was added, and the cloudy mixture was stored overnight in the refrigerator. Crystals formed and were isolated in two crops by filtration to provide 5.24 g of N-[1-(5-formyl-2-methyl-2H-pyrazol-3-yl)-1,1-dimethylethyl]benzamide as a white powder, mp 150-151° C.
