Procedure

A mixture of 7-(2-bromophenyl)-1-(3-(thiazol-2-yl)benzyl)azepan-2-one (preparation described in example 450; 50 mg; 0.11 mmol), commercially available 4-(tributylstannyl)thiazole (51 mg; 0.13 mmol), and PdCl2(PPh3)2 (8 mg; 0.011 mmol) in THF (1 ml) was heated to 75° C., under nitrogen, for 18 h. After cooling to rt, water and AcOEt were added. The separated aq. layer was further extracted with AcOEt. The mixed organic layers were washed with brine, dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure. Subsequent purification by preparative HPLC afforded the target compound. LC-MS (conditions A): tR=0.84 min.; [M+H]+: 446.14 g/mol.
