Into a 50-mL round bottom flask, was placed a solution of N-(3-(trifluoromethyl)benzyl)-2-(2-amino-5-fluoro-phenyl)isonicotinamide (200 mg, 0.51 mmol, 1.00 equiv) in N,N-dimethylformamide (2 mL), 3-((3-tert-butoxy-3-oxopropylthio)methyl)benzoic acid (200 mg, 0.68 mmol, 1.50 equiv), EDC.HCl (0.18 g, 0.94 mmol, 2.00 equiv), and 4-dimethylaminopyridine (58 mg, 0.48 mmol, 1.00 equiv). The resulting solution was stirred for 2 h at room temperature. The reaction progress was monitored by LCMS. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:5˜ethyl acetate). The product was obtained as 100 mg (29%) of a yellow solid.
