Procedure

A mixture of 3-[6′-methyl-4′-(4-trifluoromethyl-phenyl)-[2,2′]bipyridinyl-6-yl]-benzenesulfonamide (example 266) (300 mg, 0.639 mmol), N-ethyldiisopropylamine (0.22 ml, 1.278 mmol) and methoxyacetyl chloride (0.067 ml, 0.639 mmol) in dichloromethane (3 ml) was stirred at 23° C. for 16 h. Diluted with dichloromethane, washed with water, dried the organic layer over MgSO4. Removal of the solvent in vacuum left a crude product, which was purified by silica gel column chromatography with n-heptane/EtOAc, followed by trituration with diethyl ether to give the title compound (46 mg, 13%) as a white solid. MS (ISP) 542.7 [(M+H)+]; mp 188° C.
