Reaction Steps

To a solution of the crude 4-(2-{5-allyloxycarbonylamino-2-cyano-6-[(spiro[3.5]non-7-ylmethyl)amino]pyrimidin-4-yloxy}ethyl)piperidine-1-carboxylic acid tert-butyl ester (230 mg) in THF (10 mL) are added trietylamine (1.25 mmol) and Pd(PPh3)4 (catalytic amount) at room temperature under N2 atmosphere. After stirring at the same temperature for 1 h, the reaction mixture is diluted with AcOEt. The organic layer is washed with H2O and evaporated in vacuo. The resulting residue is purified by silica gel column chromatography to give 4-(2-{5-Amino-2-cyano-6-[(spiro[3.5]non-7-ylmethyl)amino]pyrimidin-4-yloxy}ethyl)piperidine-1-carboxylic acid tert-butyl ester; 1H-NMR (CDCl3), δ: 0.97-1.07 (2H, m), 1.13-1.28 (4H, m), 1.42-1.88 (25H, m), 2.69 (2H, t), 3.22 (2H, s), 3.31 (2H, t), 4.04-4.16 (2H, m), 4.40 (2H, t), 4.51 (1H, t).
