실험 절차
Homopiperazine (70 g., 0.70 mole) in 160 ml. water was treated with 6 N hydrochloric acid to adjust to pH 5.5 Furoyl chloride (79.5 g., 0.60 mole) and 25% (w/w) aqueous sodium hydroxide solution were added simultaneously to maintain a pH of 4.5-5.5. Then additional sodium hydroxide was added to bring the mixture to pH 9.5. The solution was extracted with chloroform, dried over anhydrous potassium carbonate and distilled to afford 63 g. of product, B.P. 124°-130° C. at 10 mm.
