Reaction Steps

To a solution of 2-chloro-5-nitropyridine (25 g) and 2-(5-methyl-2-phenyl-4-oxazolyl)ethanol (32.1 g) in THF (250 ml) was added, in small portions, sodium hydride (60% in oil, 6.92 g), and the mixture was stirred. The reaction mixture was stirred, at room temperature, for further 15 hours, which was poured into water, followed by extraction with ethyl acetate. The ethyl acetate layer was washed with water and dried (MgSO4), then the solvent was distilled off under reduced pressure. The residual crystals are collected by filtration, followed by recrystallization from ethanol to afford 2-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]-5-nitropyridine (25.4 g, 49%) as yellowish brown crystals, m.p.110.5°-111.5° C.
