Reaction Steps
A mixture of 2,4-dinitrophenol (4.6 g, 80 wt %), potassium carbonate (4.2 g), NMP (40 mL) and 1,4-dibromo-2-butene (12.8 g) was heated to 450° C. for 2 hr. Extraction in the normal fashion and Kugelrohr distillation of the excess dibromide (0.1 mm Hg, 80° C.) gave 1-bromo-4-(2,4-dinitrophenyloxy)but-2-ene (3.7 g, mp 55-57° C.).
