Procedure

232.7 g of 1,6-naphthalene diol, 409.5 g of 4-fluoronitrobenzene and 402.1 g potassium carbonate were combined with 1 1. of dimethylacetamide (DMAc) and heated to reflux for 1 hour to form 1,6-bis-(4-nitrophenoxy) naphthalene. The mixture was concentrated by distilling off 500 ml of DMAc. The mixture was cooled to room temperature and the product precipitated by pouring into 1 1. of water. A light tan solid was collected and washed with three 500 ml portions of methanol to facilitate drying.
