When the Mannich reaction between 1-keto-1,2,3,4-tetrahydrophenanthrene (Ⅰ),diethanolamine hydrochloride and 36% aqueous solution of formaldehyde was carried out in 95% ethanol solution,three products were isolated.The main one is the hydrochloride of 1-keto-2-[N-bis (β-hydroxyethyl)-aminomethylene]-1,2,3,4-tetrahydrophenanthrene (Ⅱ),and two nitrogen-free by-products,namely 1-keto-2-methylene-1,2,3,4-tetrahydrophenan-threne (Ⅲ) and its dimer (Ⅴ).
