Abstract

After cooling and acidifying to PH 1, the precipitate was filtered and dried to give 0.68 g. of crude, orange material melting at 208-214'. This material was twice recrystallized from ethanol-water (1: l), treating with charcoal, to give 0.45 g.(: 8.4 y0 of theory) of pale yellow needles melting at 220-221.
