Reaction Steps

In an argon atmosphere, tri(dibenzylideneacetone)dipalladium (4.85 mg, 0.00530 mmol), 1,1′-bis(diphenylphosphino)ferrocene (9.09 mg, 0.0159 mmol) and cesium carbonate (48.2 mg, 0.148 mmol) were added to a toluene solution (1 mL) containing N-(piperidin-3-yl)-2-[2-(4-chlorophenyl)-4-methylthiazol-5-yl]acetamide (37.2 mg, 0.106 mmol) and methyl 2-iodobenzoate (27.8 mg, 0.106 mmol). This reaction mixture was stirred at 100° C. for 8 hours. Subsequently, the mixture was allowed to cool and was filtered through Celite. The filtrate was purified by silica gel column chromatography (hexane:ethyl acetate=2:1->1:1) to give 23.0 mg (45%) of the desired compound as a colorless oil.
