Reaction Conditions

Reaction Steps

A solution of 2-chloro-6-methoxy-3-nitropyridine (5.20 g, 27.6 mmol) in DMF (50 mL) was treated with 2-tert-butylphenol (4.9 mL, 31.7 mmol) and cesium carbonate (27.0 g, 82.8 mmol). The mixture was heated at 80° C. for 18 h. The reaction was allowed to cool to rt, the mixture was poured into water (500 mL) with stirring. The brown precipitate formed was filtered and washed with water, and recrystallized twice from ethanol to afford 2a as brown crystals (6.66 g, 80%). [M+H]+=303.2.
