1,4-Bis(2-ethylhexyloxy)-2-nitrobenzene (11.4 g, 0.03 mol) is dissolved in 2-propanol (100 ml) and degassed under vacuum, purging to nitrogen. 10% (w/w) Pd/C (0.52 g) is added and the mixture heated to 80° C. Water (10 ml) is added, followed by solid ammonium formate (18.9 g, 0.3 mol). After a further 1 hour at 80° C., the reaction mixture is allowed to cool then filtered to remove catalyst, to give a colourless solution which darkened rapidly on standing. The material is used immediately as an isopropanol solution (quant).
