Participants

Reaction Steps

To a suspension of 4-methyl-3-(trifluoromethoxy)phenol (Intermediate 29, 364 mg, 1.89 mmol) and 2 chloro-5-nitropyridine (300 mg, 1.89 mmol) in acetonitrile (4 mL) was added K2CO3 (653 mg, 4.72 mmol) at room temperature. The mixture was heated at reflux for 18 hrs until completion. The resulting mixture was cooled down to room temperature, diluted with water (10 mL) and ethyl acetate (10 mL). Phases were separated, the organic layer was washed with an aqueous 10% solution of ammonium chloride (10 mL) and aqueous 13% solution of NaCl (10 mL). The organic layer was dried over Na2SO4 and evaporated to dryness to give the title compound (594 mg) as pale brown oil.
