A series of aporphine nitrogen mustards and their congeners (lb-g) has been prepared. N- [[Bis (2-chloroethyl)-amino] acetyl]-2, 11-dihyroxy-lO-methoxynoraporphine (lb) and its mono- and diacetyl ester derivatives (lc-d) were prepared from N-(chloroacetyl)-2, 1l-diacetoxy-lO- methoxynoraporphine (2). Reaction of 2 with diethanolamine under various conditions and different solvents resulted in the corresponding N-[[bis (2-hydroxyethyl) amino] acetyl] ...
