Procedure
p-Nitrophenol (139 g, 1.0 mol) was dissolved in 1.5 l 0.8M sodium hydroxide. Epichlorohydrin, IX, (117 ml, 1.5 mol) was added and the mixture stirred vigorously overnight. The homogenous solution was then extracted three times with 300 ml chloroform and the organic fractions combined and dried over magnesium sulfate. After removal of the drying agent by filtration, evaporation of the filtrate gave a yellow oil which crystallized on standing. The oily crystals were triturated with methanol and filtered to yield 55.6 g of the desired compound as white crystals shown to be homogenous by thin layer chromatography (60:40 ethyl acetate/hexanes, Rf =0.77) m.p. 62°-65° C.
