Reaction Steps
To a solution of 2-p-tolyl-3-trifluoromethyl-pyridine (8.4 mmol) in H2SO4 (6 mL) cautiously add fuming HNO3 (2 ml). Stir the mixture for 60 minutes at room temperature. Pour the mixture onto ice-water (30 mL), extract with EtOAc, neutralize with 1 N NaOH, dry over Na2SO4, and concentrate under vacuum to obtain 2-(4-methyl-3-nitro-phenyl)-3-(trifluoromethyl)-pyridine.
