Procedure

4-Methyldibenzofuran (30 g, 165 mmol) and sodium carbonate (17.5 g, 165 mmol) were mixed in hexane (300 ml) and bromine (26.4 g, 165 mmol) was added. The reaction was stirred at room temperature for 72 hours, then the solvent was removed in vacuo to give an oil which crystallised. Recrystallisation from IMS yielded several batches of off-white crystals (31.22 g, 72%) with m.p. 124°-125° C. (Found: C, 58.59; H, 3,28. C13H9BrO 0.31H2O requires: C, 58.58; H, 3.63%); δH [2H6 ]-DMSO 8.15 (1H, d), 7.9 (1H, d), 7.7 (1H, d), 7.4 (1H, t), 7.05 (2H, m), 2.6 (3H, s); m/z 260/262 (M+).
