実験手順

A mixture of 65 parts of 3-pyridinemethanamine, 94 parts of 1-chloro-2-nitrobenzene, 80 parts of sodium carbonate and 800 parts of 1-butanol is stirred and refluxed over week-end. The reaction mixture is cooled, filtered and the filtrate is evaporated. The residue is purified by column-chromatography over silica gel using a mixture of trichloromethane and methanol (98:2 by volume) as eluent. The pure fractions are collected and the eluent is evaporated. The residue is crystallized from 2,2'-oxybispropane. The product is filtered off and dried, yielding 33 parts (23%) of N-(2-nitrophenyl)-3-pyridinemethanamine.
