Procedure

To a solution of N2-(2,3-dimethyl-2H-indazol-6-yl)-5-methyl-N4-(3-azaspiro[5.5]undecan-9-yl)pyrimidine-2,4-diamine (203.2 mg, 0.4843 mmol), HOAT (105.8 mg, 0.7773 mmol) and EDCI (144.5 mg, 0.7538 mmol) in DCM/DMF (4 mL/1 mL) were added N,N-diethylethanamine (209.1 mg, 2.066 mmol) and 2-cyanoacetic acid (48.1 mg, 0.565 mmol). The reaction was stirred at rt for 2.5 h and then concentrated in vacuo. The residue was purified by silica gel column chromatography (DCM/MeOH (v/v)=30/1) to give the title compound as a light pink solid (48.4 mg, 20.4%).
