“…By recrystallization of residue (a) from mixtures of chloroform, benzene, and petroleum ether, as well as acetone and ether, a total of 0.106 g. melting at 228-232°w as obtained. No satisfactory purification could be achieved when residue (6) was subjected to recrystallization. It was therefore decided to combine residue (6) with the filtrates from the recrystallization of residue (o) and to subject the total to chromatographic adsorption.…”
