실험 절차

To a stirred solution of 5-chloro-thiophene-2-carboxylic acid {(S)-4-[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-2-methylamino-cyclopentyl}-amide (36 mg) in acetonitrile (2 ml) were added N-ethyldiisopropylamine (0.03 ml) and mesyl chloride (0.01 ml). The reaction mixture was stirred at r.t. for 3 hrs, then concentrated. The crude product was purified by column chromatography (silica gel; gradient: CH2Cl2→CH2Cl2/MeOH 92:8) to give 5-chloro-thiophene-2-carboxylic acid [(S)-4-[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-2-(methanesulfonyl-methyl-amino)-cyclopentyl]-amide (32 mg) as off-white solid. MS 567.2 ([M+H]+).
