Reaction Steps

A mixture of 1-[(3-chloro-4-nitrophenyl)methyl]-4-methylpiperazine (0.313 g, 1.16 mmol), methyl 5-amino-3-({(1R)-1-[2-(trifluoromethyl)phenyl]ethyl}oxy)-2-thiophenecarboxylate (0.401 g, 1.16 mmol), K2CO3 (0.401 g, 2.90 mmol), X-Phos (0.0587 g, 0.12 mmol), tris(benzylideneacetone)dipalladium(0) (0.0531 g, 0.06 mmol) and tert-butanol (4.6 mL) in a sealed tube was heated at 80° C. for 18 h. The crude reaction mixture was filtered through celite, washing with toluene and then purified by flash column chromatography (EtOAc:MeOH:NEt3) to give the title compound (0.534 g, 70%) as a red amorphous solid.
