Yield: 91%
Reaction Conditions:
with pyridine at 20; for 16 h;Cooling with ice;
Steps:
1 Step 1 : (1 -Methanesulfonyl-piperidin-4-yl)-carbamic acid tert-butyl ester
5.00 g (25.0 mmol) of BOC-4-aminopiperidine are dissolved in pyridine (19.8 mL) and cooled in an ice bath. 2.13 mL (27.5 mmol) of methanesulfonyl chloride are added slowly. The reaction is stirred at RT for 16 h. After diluting with water, the reaction is extracted with DCM. Organic layers are washed with water, dried with MgS04 and filtered. The solvent is removed under reduced pressure to afford 6.30 g of (1 -Methanesulfonyl-piperidin-4-yl)-carbamic acid tert-butyl ester. Yield: 91 %; ESI-MS: 279 [M+H]+
