1-Fluoro-2-methyl-4-nitrobenzene (11 g, 70.9 mmoles) is refluxed for 5 hours with 41.5 g (0.41 moles) of tetrahydrofurfurylamine. After that, the reaction product is poured onto 400 g of ice/water and the solid obtained is filtered off. Recrystallization from ethanol/water results in a yellow, grainy dye with a melting point of 56°-58° C.
