실험 절차

[1-(4-Methylamino-benzenesulfonyl)-piperidin-4-yl]-carbamic acid tert-butyl ester (0.13 g, 0.35 mmol) was dissolved in THF (5 ml). To this was added diisopropylethylamine (0.18 ml, 0.7 mmol) in one portion followed by the drop wise addition of tetrahydro-2H-pyran-4-carbonyl chloride (0.06 ml, 0.38 mmol) and the mixture was stirred at room temperature under a nitrogen atmosphere for 3 hours. After this time the mixture was concentrated, diluted with DCM (200 ml) and washed sequentially with HCl (1M solution, 10 ml), NaOH (1M solution, 10 ml) and brine (10 ml). The organic layer was separated, dried (MgSO4), filtered and concentrated to give the title compound (0.17 g, 98% yield) as a white powder which was taken on without further purification. Tr=1.89 min m/z (ES+) (M+Na+) 504.
