Procedure

step 5—To a solution of 54 (156 mg, 0.415 mmol) in pyridine (5 mL) at 0° C. was added methanesulfonyl chloride (0.050 mL, 0.643 mmol). The reaction was gradually warmed to RT and stirred for 1.5 h then diluted with EtOAc. The organic layer was washed sequentially with saturated aqueous CuSO4, brine, dried (Na2SO4), filtered and concentrated. The crude residue was purified by SiO2 chromatography eluting with an EtOAc/hexane gradient (10 to 50% EtOAc) to afford 115 mg (61%) of N-(4-{2-[5-tert-butyl-2-hydroxy-3-(2-methoxy-pyridin-3-yl)-phenyl]-ethyl}-phenyl)-methanesulfonamide (56) as a colorless oil.
