![Diacetyliao&^ogelsemine Hydrochloride, C20H 22 ON2(OAc)2,HC1.— This derivative was prepared in the same manner as the above- described diacetylapogelsemine hydrochloride. Unlike the latter compound, it is very sparingly soluble in boiling absolute alcohol, but dissolves readily in hot 95 per cent, alcohol, separating in glistening plates, which contain one molecule of water of crystallisar tion, and melt at 305°: 0 1460 gave 0-3236 COo and 0'0870 HoO. C = 60 4; H=6 6. 0-2706 „ 0-0810 AgCl. Cl = 7-4. C24Ho90r,N2Cl,Ho0 requires C=60-2; H = 6-4; Cl = 7-4 per cent. 0 2304, made up to 20 c.c. with water, gave Oj, -f0°34' in a 2-dcm. tube, whence [o]p -f24-6°. Diacetyliso&T^ogehemine was prepared from its hydrochloride, but could not be crjrstallised. No monoacetyl derivative could be obtained from it.
