YieldReaction ConditionsOperation in experiment
99% With trifluoroacetic acid In dichloromethane at 20℃; for 16 h; 6.30 g (22.63 mmol) of (1-methanesulfonyl-piperidin-4-yl)-carbamic acid tert-butyl ester are dissolved in DCM (74 mL) and 17.4 mL (226 mmol) TFA are added.
The reaction is stirred at RT for 16 h.
The solvent is removed under reduced pressure.
The crude product is diluted with diethylether at 40° C., the precipitate is filtered, washed with water and dried.
The product is dissolved in MeOH, polymer supported hydrogencarbonate (PL-HCO3 MP Resin, Agilent Technologies) is added and the suspension is stirred for a few minutes.
The resin is filtered and the solvent is removed under reduced pressure to afford 4.00 g of 1-methanesulfonyl-piperidin-4-ylamine. Yield: 99percent; ESI-MS: 179 [M+H]+; HPLC (Rt): 0.26 min (method E)

80% With trifluoroacetic acid In dichloromethane at 20℃; for 1.5 h; Intermediate 7: 1-(methylsulfonyl)piperidin-4-amine
To a solution of tert-butyl (1-(methylsulfonyl)piperidin-4-yl)carbamate (2.72 g; 9.77 mmol) in DCM (30 mL) was added TFA (10.6 mL; 143 mmol).
The mixture was stirred at r.t. for 1.5 hours and concentrated in vacuo.
The residue was triturated with diethyl ether (30 mL), filtered, and washed with diethyl ether (30 mL).
The solid was dissolved in H2O (60 mL), basified with aqueous NaOH to pH=11, and extracted with DCM/i-PrOH (10/1, 60 mL*10).
The combined organic layers were dried over anhydrous Na2SO4, filtered, and concentrated to afford 1.4 g (80percent) of the title compound as a yellow oil. LC-MS: m/z 179.0 [M+H]+. 1H NMR (300 MHz, CDCl3) δ [ppm]: 3.50-3.38 (m, 2H), 2.82 (s, 3H), 2.80-2.61 (m, 3H), 1.80-1.70 (m, 2H), 1.33-1.23 (m, 2H).
