Procedure

The title compound was prepared according to the procedure of Example 7 using 2-n propylphenol (30 g, 0.22 mol) in methylene chloride (400 ml), sodium hydroxide (18.8 g, 0.44 mol) in water (400 ml), 1,3-dibromopropane (100 g, 1 mol) and tetra-n butylammonium bisulfate (80 g, 0.22 mol). Distillation of the crude product yielded 55 g (75%) of pure material, b.p 85°-87° (0.1 mm Hg).
