실험 절차

Compound B (106 g) was dissolved in methanol (1.35 l) and hydrogenated at atmospheric pressure over 10% palladium on charcoal catalyst (10.6 g). When hydrogen uptake was complete, the catalyst was removed by filtration through diatomaceous earth. Volatile material was then removed from the filtrate by evaporation to give 5-amino-2-[2-(t-butyldiphenylsilyl)oxyethoxy]pyridine (C) (99.4 g), as an oil which was used without further purification; NMR (d6 -DMSO): 0.95(s,9H), 3.9(t,2H), 4.25(t,2H), 4.7(brs,2H), 6.5(d,1H), 7.0(dd,1H), 7.35-7.75 (complex m,7H), 7.6-7.75(m,4H).
