Reaction Steps
30.0 g of 2,2,3-triphenyltetrahydrofuran are dissolved in 125 ml of acetic acid, after which 25 ml of 40% hydrogen-bromide in acetic acid are added. The mixture is stirred for 1 h at 75° C. The solvent is evaporated,and 1M sodium carbonate solution is added in excess. The product is extracted in toluene. The toluene solution is dried over sodium sulfate and the solvent is evaporated. The product is recrystallized from aqueous methanol and then has m.p 81-3° C. The yield is 28.7 g (84%).
