Procedure
The title compound was prepared using a procedure analogous to that described in EXAMPLE 127, Step A substituting 5-bromo-2-(4-bromo-2-methylphenyl)thiophene (from Step B) for 4-bromo-2-methyliodobenzene and 3-cyano-4-fluorophenylzincbromide for 2-thienylzinc bromide: 1H NMR (CDCl3) 7.85 (m, 2H), 7.47 (d, J=2.0, 1H), 7.40 (dd, J=2.0, 9.0, 1H), 7.29 (m, 3H), 7.07 (d, J=6.5, 1H), 2.47 (s, 3H).
