Procedure

2-chloro-5-nitropyridine (114 mg, 0.716 mmol, 1 equiv) was dissolved in 3 mL of dimethylformamide. 3-(ethyloxy)-4-methylphenol (Intermediate 90, 109 mg) and potassium carbonate (198 mg, 1.432 mmol) were added. The reaction mixture was stirred at room temperature 3 hours. The reaction mixture was filtered. The filtrated solid was washed with dichloromethane. The volatiles were evaporated under vacuum. Ethyl acetate and brine were added to the residue. The compound was extracted 2 times with ethyl acetate and 2 times with dichloromethane. The gathered organic phases were dried over sodium sulphate, filtered and evaporated to afford the title compound which was used directly in the next step (113 mg).
