Reaction Steps

To a rapidly stirred solution of 2-((6-chrysenylmethyl)amino)-2-methyl-1,3-propanediol hydrochloride (1B, 20 g, 52.36 mmol) in a mixture of CH3OH (200 mL) and H2O (800 mL) was added dropwise over 10 min a 1N NaOH solution (55 mL). The resulting white precipitate was filtered and washed with warm H2O (4×500 mL) and then with Et2O (1 L), sucked dry and placed in a vacuum overnight. A total of 17.43 g (96.4%) of 2-((6-chrysenylmethyl)amino)-2-methyl-1,3-propanediol mp 200°-202°, (C, H, N) was obtained.
