Reaction Steps

A mixture of dibenzofuran (93.5 g, 0.557 M), trioxane (20 g, 0.222 M) and myrystyltrimethylammonium bromide (6.2 g, 18.5 mmol) in 1 L acetic acid and 135 mL of 48% HBr was stirred at 50-60° C. for 28 h, then concentrated; the residue was dissolved in CH2Cl2, washed with water, dried over Na2SO4, evaporated to give the crude bromide 1a. Compound 1a was used without further purification in the next step.
