Procedure

TEA (2.43 mL, 17.46 mmol) and methanesulfonylchloride (2.0 g, 17.46 mmol). were added to a solution of piperidin-1-ylamine Compound 1i1 (1.75 g, 17.46 mmol) at 0° C., under a N2 atmosphere. The mixture was stirred for 3 hrs, while warming to r.t. The reaction was quenched with water (20 mL) and the organic layer was diluted with CH2Cl2 (100 mL), washed with water and brine, separated and dried with anhydrous sodium sulfate, then filtered and concentrated in vacuo to yield N-piperidin-1-yl-methanesulfonamide Compound 1i2 as an oil.
