Reaction Steps
2-Aminophenol (6 g; 54 mmol) is dissolved in 1-butanol (110 ml) in the presence of sodium carbonate (2.9 g; 27.5 mmol) and N-methylbis(2-chloroethyl)amine hydrochloride (11.1 g; 58 mmol). The suspension is heated at 123° C. for 3 days. The butanol is evaporated off under reduced pressure and compound 43A is purified by flash chromatography with the following mixtures of eluents: NH4 OH/acetone/CH2Cl2 (0.5/20/80) and then NH4 OH/methanol/CH2Cl2 (1/5/95).
