A mixture of 2-bromophenol (23.2 mL, 0.20 mol), potassium carbonate (33.2 g, 0.24 mol) and 2-bromopropane (28.0 mL, 0.30 mol) in dimethylformamide (200 mL) was stirred in a preheated oil bath (60° C.) for 5 h. The cooled reaction mixture was then partitioned between ether and water. The layers were separated and the aqueous phase was extracted with ether. The combined organic solution was washed with copious amounts of water, 3N aqueous NaOH, dried (MgSO4), filtered and concentrated in vacuo to furnish 39.3 g (91%) of XIV as a pale yellow oil which was carried on without further purification. The structure was supported by GC/MS and 90 MHz 1H NMR.
