反応手順
To a stirred solution of 2.55 g. of sodium penicillanate 1,1-dioxide in 20 ml. of water was added 3.80 g. of tetrabutylammonium bisulfate. Stirring was continued for 5 minutes and then 20 ml. of chloroform was added. The pH was adjusted to 6.8 with saturated aqueous sodium bicarbonate and then the aqueous layer was saturated with sodium sulfate. The layers were separated and the aqueous layer was extracted with chloroform. The combined chloroform solutions were dried using sodium sulfate and then evaporated in vacuo to give the tetrabutylammonium salt of penicillanic acid 1,1-dioxide.
