Procedure

To a solution 2-(4-bromo-2-fluorophenyl)-3-{4-[2-(2,6-dichloro-4-methylphenoxy)ethoxy]phenyl}propanenitrile (1 eq.) from step 1 and 2-chlorophenylboronic acid (2 eq.) in tert-butanol (0.16M) at room temperature was added palladium acetate/triphenyl phosphine (1:3; 0.05 eq.) and aqueous Na2CO3 (2M; 4 eq.). The mixture was stirred at 80° C. for 12 h, cooled to room temperature, poured in water and extracted with EtOAc. The organic extract was washed with brine, dried over MgSO4 filtered and concentrated. Purification by column chromatography on silica gel, eluting with Hex/Tol (55 to 65%) afforded the desired compound.
