Procedure

Into a 10-mL vial, was placed a solution of 3-((3-tert-butoxy-3-oxopropylthio)methyl)benzoic acid (355.2 mg, 1.20 mmol, 2.00 equiv) in dichloromethane (5 mL), EDC.HCl (228 mg, 1.19 mmol, 2.00 equiv), 4-dimethylaminopyridine (146.4 mg, 2.00 mmol), and N-(3-(trifluoromethyl)benzyl)-2-(2-amino-5-(dipropylamino)phenyl)isonicotinamide (300 mg, 0.64 mmol, 1.00 equiv). The resulting solution was stirred for 2 h at 25° C. in an oil bath. The resulting solution was diluted with 50 mL of dichloromethane and washed with 3×50 mL of aqueous NH4Cl. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:5-1:3). The product was obtained as 320 mg (67%) of a yellow to green oil.
