Procedure

To a solution of the above product, 4-[2-(5-benzylcarbamoyl-6-chloro-2-methanesulfonylpyrimidin-4-yloxy)ethyl]piperidine-1-carboxylic acid tert-butyl ester in CH2Cl2/H2O (20 mL/2 mL) is added NaCN (3.3 mmol) and tetra-n-butylammonium bromide (0.14 mmol) at 0° C. After warmed up to room temperature, the reaction mixture is vigorously stirred for 1.5 h at room temperature. The mixture is diluted with CH2Cl2, washed with aq. NaHCO3. The organic layer is dried over Na2SO4, filtered, and concentrated. The residue is purified by silica gel column chromatography to give 4-[2-(5-benzylcarbamoyl-6-chloro-2-cyano-pyrimidin-4-yloxy)ethyl]piperidine-1-carboxylic acid tert-butyl ester as a white solid. 1H-NMR (CDCl3), δ 1.09-1.19 (2H, m), 1.46 (9H, s), 1.63-1.74 (5H, m), 2.66 (2H, br t), 4.07 (2H, m), 4.51 (2H, t), 4.66 (2H, d), 6.11 (1H, t), 7.31-7.37 (5H, m).
