実験手順

tert-Butyl {(3S)-1-[(3-chloro-2-methylphenyl)sulfonyl]piperidin-3-yl}carbamate (58.34 mg, 0.0001500 mol) was treated with 4.0 M of hydrogen chloride in 1,4-dioxane (1.0 mL) at rt for 30 min. The solvent was evaporated under reduced pressure and the residue was dissolved in DMF (1.0 mL) and to this was added benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (69.6 mg, 0.000157 mol), 4-methylmorpholine (100.0 uL, 0.0009096 mol), and (3S)-1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (34.4 mg, 0.000150 mol) at rt. After stirring for 1 h, the reaction mixture was diluted with ethyl acetate (5 mL) and washed with NaHCO3 (7.5%, 3×2 mL) and brine (3×20 mL). The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure to give the desired product which was used directly in the next step without further purification.
