HCID 695624-Nitro-2-(trifluoromethyl)anisoleYield 99%

Procedure

Sodium (11.78 g, 0.512 mol) was dissolved in dry methanol (1 l) and to the resulting solution was added a solution of 1-chloro-4-nitro-2-trifluoromethyl-benzene (96.22 g, 0.427 mol) in methanol (100 ml). The reaction mixture was refluxed for 3 h then cooled and evaporated in vacuo. The residue was partitioned between water (500 ml) and dichloromethane (3×400 ml). The combined organic extracts were dried (Na2SO4) and evaporated to give the title compound (93.76 g, 99%) as a white solid.
