実験手順

To a degassed suspension of [2-(4-bromo-2,5-dichloro-phenoxy)-pyridin-3-yl]-(4-cyclopropyl-3,4-dihydro-2H-quinoxalin-1-yl)-methanone (100 mg, 0.19 mmol, 1.0 equiv; Example 163) in triethylamine (0.73 g, 1.0 mL, 7.21 mmol, 38.0 equiv; [CAS RN 121-44-8]) under Ar was added 2-chloro-4-ethynyl-benzoic acid methyl ester (120 mg, 0.62 mmol, 3.2 equiv), tetrakis(triphenylphosphine)palladium(0) (22 mg, 0.02 mmol, 0.1 equiv; [CAS RN 14221-01-3]) and copper(I) iodide (3.7 mg, 0.02 mmol, 0.1 equiv; [CAS RN 7681-65-4]). The reaction mixture was heated by microwave irradiation to 100° C. for 40 min. Removal of the solvent mixture under reduced pressure and purification by preparative HPLC on reversed phase (Xterra® PrepMSC 18, 5 μm, 19×50 mm column equipped with a Gilson Liquid Handler 215 autosampler, two Rainin Dynamax® SD-300 pumps, a Sedex ELSD 75 lightscatter and a Dionex UVD 340S UV detector) and eluting with a gradient of acetonitrile/water provided 40 mg (33%) of the title compound as a light brown powder. MS (ISP): 634.2 [M+H]+.
