실험 절차
To an ice-cooled and stirred solution of 25 grams 4-ethoxy-3-methoxyphenylacetonitrile (0.13 mmol) in 74 ml acetic anhydride (0.785 mol) was slowly added perchloric acid (70%, 11.7 N, 15.5 ml, 0.182 mol) over a 15 minute period. The dark reaction mixture slowly became a yellow slurry and was stirred at room temperature for 42 hours. The mixture was diluted with 200 ml diethyl ether and a crystalline yellow solid was isolated by filtration, washed with diethyl ether and dried in vacuo to provide 47.3 grams of Compound 8d (100% yield) having a melting point of 188°-189° C. (with decomposition).
