The title compound was prepared from 2-bromo-5-[(3-fluoro-4-methoxyphenyl)sulfonyl]-6-methyl-5,6-dihydrophenanthridine (0.5 g, 1.08 mmol), cyclohexene, (0.27 mL, 3.58 mmol), and 1.0 M boron tribromide in dichloromethane (6.49 mL, 6.49 mmol) according to the procedure and in the same manner as described in Example 4, step b. The crude product was purified by re-crystallization from dichloromethane to yield 4-[(2-bromo-6-methylphenanthridin-5(6H)-yl)sulfonyl]-2-fluorophenol (0.15 g, 0.34 mmol, 31%) as an off-white solid, m.p. 203-206° C.;
