Procedure
To 6-amino-5-[5-({[(3-methylphenyl)amino]carbonyl}amino)-1-benzothien-2-yl]nicotinic acid (418 mg, 1 mmol, 1 equiv.) and (S)-methyl 5-(S-methylsulfonimidoyl)pentanoate (232 mg, 1.2 equiv.) in anhydrous DMF (6 mL) under nitrogen atmosphere was added diisopropylethylamine (0.348 mL, 2.0 equiv.) and (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (486.5 mg, 1.1 equiv.). The reaction mixture was heated to 60° C. and stirred for 2 hours. After the reaction was cooled to room temperature, it was diluted with EtOAc and washed sequentially with saturated aqueous NaHCO3, brine, aqueous NH4Cl, and brine. After the organic layer was dried (anhydrous Na2SO4), it was decanted, concentrated, and the brown oily residue was subject to a column chromatography (EtOAc-Hex 1:4 to 6:1). methyl 5-[N-({6-amino-5-[5-({[(3-methylphenyl)amino]carbonyl}amino)-1-benzothien-2-yl]pyridin-3-yl}carbonyl)-S-methylsulfonimidoyl]pentanoate was obtained as a yellow foam in amount of 394 mg (66%).
