Procedure

To a solution of the 4-amino-4-benzylpiperidine-1-carboxylic acid tert-butyl ester (0.38 mmol, step 66.1) and 2-cyano-4-[(spiro[2.5]oct-6-ylmethyl)amino]pyrimidine-5-carboxylic acid (0.38 mmol) in DMF (1.3 mL) are added HOAt (0.51 mmol) and EDCI-HCl (0.51 mmol) at 0° C. After warming to room temperature and stirring for 15 h, the reaction mixture is diluted with AcOEt and washed with 1N aq. KHSO4, sat. aq. NaHCO3, and brine. The organic layer is dried over MgSO4, filtered, and concentrated in vacuo. The residue is purified by silica gel column chromatography to give 4-benzyl-4-({2-cyano-4-[(spiro[2.5]oct-6-ylmethyl)-amino]-pyrimidine-5-carbonyl}amino)piperidine-1-carboxylic acid tert-butyl ester.
