Amsacrine → m-AMSA D-galacturonate

참여 물질

반응 단계

A solution of 3.93 gm of m-AMSA and 2.12 gm of D-galacturonic acid monohydrate in 325 ml of specially denatured 3A anhydrous ethanol at 70°-80° C. is filtered with suction. The filtrate is stirred and chilled to 0°-5° C., then stored at -20° C. for about 16 hours. The product is collected, washed with cold (about -20° C.) specially denatured 3A anhydrous ethanol, then with anhydrous diethyl ether and dried under reduced pressure at 50°-55° C. to give 3.9 gm of m-AMSA D-galacturonate. The salt obtained by this process retains a small amount about 3% of ethanol.
