Morpholine → 4-(4-Nitrophenyl)morpholine

Participants

Reaction Steps

1-Fluoro-4-nitrobenzene (10 g, 70.9 mmoles) is refluxed for 5 hours with 35.7 g (0.41 moles) of morpholine. After that, the reaction product is poured onto 400 g of ice/water and the solid obtained is filtered off. After a recrystallization from ethanol, a dark yellow, finely pulverized dye is obtained with a melting point of 152°-154° C.
