Reaction Steps

To a solution of 4[2-(1-tert-butoxycarbonylpiperidin-4-yl)ethoxy]-2-cyano-6-[(spiro[3.5]non-7-ylmethyl)amino]pyrimidine-5-carboxylic acid (0.23 mmol, step 75.4) and 2 M methyl amine solution (0.30 mmol) in DMF (1 mL) are added EDCI-HCl (0.34 mmol) and HoAt (0.34 mmol) at 0° C. The reaction mixture is stirred at room temperature for 1 h. After dilution with AcOEt, the mixture is washed with H2O and brine. The organic layer is dried over MgSO4, filtered, and concentrated. The residue is purified by silicagel column chromatography to give 4-(2-{2-cyano-5-methylcarbamoyl-6-[(spiro[3.5]non-7-ylmethyl)amino]-pyrimidin-4-yloxy}ethyl)piperidine-1-carboxylic acid tert-butyl ester as a white solid; 1H-NMR (CDCl3), δ: 0.98-1.07 (2H, m), 1.14-1.85 (2H, m), 1.46 (9H, s), 2.70 (2H, t), 2.93 (3H, d), 3.33 (2H, t), 4.05-4.15 (2H, m), 4.54 (2H, t), 7.80-7.85 (1H, m), 10.10-10.15 (1H, m).
