To a solution of piperidine-1,2-dicarboxylic acid 1-tert-butyl ester (0.04 mmol) in DMF (1 mL) is added HATU (0.05 mmol) and DIEA (20.12 mmol). The resulting mixture is stirred for 2 min at rt and then N5-[5-(4-methoxy-phenyl)-pyrimidin-2-yl]-2-methyl-pyridine-3,5-diamine 12 (0.032 mmol) is added. The reaction mixture is stirred at 45° C. for 12 h. The mixture is cooled down and directly purified by preparative LCMS to afford 2-{5-[5-(4-methoxy-phenyl)-pyrimidin-2-ylamino]-2-methyl-pyridin-3-ylcarbamoyl}-piperidine-1-carboxylic acid tert-butyl ester 20. MS (m/z) (M+1)+: 519.1.
