反応手順
A solution of 2,4-bis(1,1-dimethylpropyl)phenol (9.23 g, 0.039 mol) in dry tetrahydrofuran (30 mL) was stirred at room temperature under nitrogen atmosphere. Sodium hydride (1.14 g of 80% dispersion, 0.04 mol) in dry tetrahydrofuran (10 mL) was added and the mixture stirred for 30 minutes to give a clear, green solution. 4-Chloro-3-nitropyridine (5.0 g, 0.032 mol) was added and the mixture heated to 50° C. for 4 hours. The mixture was cooled and submitted to aqueous, acidic work-up. The crude product was purified by chromatogaphy on silica gel with dichloromethane eluent to give the product 3-nitro-4-(2,4-bis(1,1-dimethylpropyl)phenoxy)-pyridine in 65% yield. Analyses by proton NMR and mass spectroscopy were consistent with the proposed structure.
