Reaction Steps

To a stirred solution of 3-chloro-2-methylaniline (compound 26, 21.6 g, 0.15 mol) in n-butanol (200 ml) was added bis(2-chloroethyl)amine hydrochloride (compound 27, 30 g, 0.17 mol) at room temperature and allowed to refluxed temperature for 2 days. After cooled to room temperature Na2CO3 (9 g, 0.08 mol) was added and then reaction mixture was refluxed 30 min. The resulting mixture was filtered with n-butanol (100 ml) and collected solid was dried under reduced pressure to be obtained title compound (24.8 g, 81%) as a white solid.
