Versuchsvorschrift
A mixture of 6-amino-2-chlorotoluene (158.66 g) and bis-(2-chloroethyl)amine hydrochloride (200.0 g) in chlorobenzene (800 mL) was allowed to reflux for 3 days. After cooling, the reaction mixture was filtered and then washed with ether to give the titled compound (244.3 g) as a white powder: 1H NMR (400 MHz, DMSO-d6) δ 2.29 (s, 3H), 3.06 (m, 4H), 3.22 (m, 4H), 7.05 (dd, J=2.0, 6.8 Hz, 1H), 7.17-7.23 (m, 2H), and 9.40 (br s, 2H).
