実験手順

To a suspension of 3-(3-tert-butyldimethylsilyloxypyridin-2-yl)-aniline (303 mg), N,N′-bis(tert-butoxycarbonyl)thiourea (335 mg) and diisopropylethylamine (0.405 ml) in dichloromethane (10 ml) was added 1-methyl-2-chloropyridinium iodide (335 mg), and the mixture was stirred for 18 hours. The mixture was diluted with ethyl acetate, washed with water and brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography (silica gel, 35 g, 20% ethyl acetate in n-hexane) to give N,N′-bis(tert-butoxycarbonyl)-N″-(3-(3-tert-butyldimethylsilyloxypyridin-2-yl)phenyl)guanidine (486 mg).
