Procedure

To a suspension of 5-(4-methoxypyridin-2-yl)-2-methylaniline (200 mg), N,N′-bis(tert-butoxycarbonyl)thiourea (310 mg) and diisopropyl-ethylamine (0.374 ml) in dichloromethane (10 ml) was added 1-methyl-2-chloropyridinium iodide (310 mg), and the mixture was stirred for 2 hours. The mixture was diluted with dichloromethane, washed with water and brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography (silica gel 25 g, n-hexane:ethyl acetate=3:1) to give N,N′-bis(tert-butoxycarbonyl)-N″-(5-(4-methoxypyridin-2-yl)-2-methylphenyl)guanidine (357 mg).
