実験手順

Prepared analogously to the method described in Example D above from 3-(n-butoxy)phenol (16.6 g; 0.1 mol; from Example B above) and 1,2-dibromoethane (100 ml; 1.16 mol). Following work up, the residue was chromatographed on silica gel with diisopropyl ether as eluent. The resultant oil was distilled to to yield 23.1 g (85%) of the title compound as an oil which subsequently crystallised (98% purity). bp 105-108° C. (0.01 mm Hg) mp 32-34° C. MW=273 (GC-MS)
