Reaction Steps

To solution of (1-{3-[6-(1-Methanesulfonyl-1-methyl-ethyl)-quinolin-8-yl]-phenyl}-ethyl)-(4-methylsulfanyl-phenyl)-amine from EXAMPLE 44 (Step 1) (1.0 eq) in pyridine (0.38M) was added 3,4-dichloro-benzenesulfonyl chloride (3.2 eq). The resulting mixture was stirred at 80° C. for 12 h, cooled to room temperature, poured in saturated aqueous NaHCO3 and extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated. Flash chromatography (CH2Cl2:EtOAc; 9:1) afforded the desired compound as a foam.
