(2,6-Dimethyl-phenyl)-(1-{6-[1-(2-isopropyl-phenylimino)-ethyl]-pyridin-2-yl}-ethylidene)-amine 8 (1.0 g, 0.0026 mol) was added in one portion to the suspension of 0.31 g (0.0025 mol) of iron (II) chloride in 50 ml of THF at ambient temperature in nitrogen glove box. The reaction mixture was stirred for 12 h. The resultant blue solid was filtered and washed by 50 ml of pentanes three times and dried under 1-mm vacuum overnight. The yield of (2,6-dimethyl-phenyl)-(1-{6-[1-(2-isopropyl-phenylimino)-ethyl]-pyridin-2-yl}-ethylidene)-amine iron (II) chloride 10 was 1.06 g (85%).
