Procedure

A mixture of 40 parts of 5-methyl-2-furanmethanamine, 46 parts of 1-chloro-2-nitrobenzene and 210 parts of N,N-diethylethanamine was stirred and refluxed for 2 days. The reaction mixture was evaporated, water was added and the product was extracted with dichloromethane. The extract was dried, filtered and evaporated. The residue was purified by filtration over silica gel using trichloromethane as eluent. The filtrate was evaporated, yielding 62 parts (89%) of 5-methyl-N-(2-nitrophenyl)-2-furanmethanamine as a residue (intermediate 2).
