反应详情

A solution of N-(5-chloropentyl)-2,3-dimethyl-5-nitro-6-phenoxypyridin-4-amine (30.86 g, 85 mmol) in toluene (200 mL) was added to a Parr vessel containing a mixture of 5% platinum on carbon (25.24 g) and toluene (100 mL). The vessel was placed under hydrogen pressure (30 psi, 2.0×105 Pa) and allowed to shake overnight. The reaction mixture was filtered through a layer of Celite® filter aid. The filtrate was concentrated under reduced pressure to provide 24.97 g of N4-(5-chloropentyl)-5,6-dimethyl-2-phenoxypyridine-3,4-diamine as a thick off white oil.
