実験手順

Concentrated hydrochloric acid (10 ml) was added to 1.5 g (4.93 mmol) of methyl 3-[4-[N,N-bis(2-chloroethyl)amino]phenyl]propionate, followed by stirring under heat for 2.5 hours over an oil bath controlled at 90° C. The reaction mixture was diluted with water and was then adjusted to about pH 2 or so with a 5N aqueous solution of sodium hydroxide. The resultant crystals were collected by filtration, whereby 1.21 g (4.17 mmol) of the title compound were obtained as white crystals (yield: 84.6%).
