실험 절차

To a solution of tert-butyl (3S,5R)-3-[[[1-(2-hydroxyethyl)-1H-benzimidazol-2-yl]carbonyl](2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (223 mg) and triethylamine (84 μl) in THF (5 ml) was added dropwise methanesulfonyl chloride (37 μl) at room temperature. The reaction mixture was stirred at room temperature for 3 hr, diluted with aqueous sodium bicarbonate, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the object product (288 mg).
