N,N-Diisopropylethylamine (9.3 μL, 0.054 mmol) was added to a mixture of {4-[6-(2,6-dichloro-3,5-dimethoxyphenyl)-1H-pyrazolo[4,3-c]pyridin-3-yl]-1H-pyrazol-1-yl}acetic acid (8.0 mg, 0.018 mmol), 2.0 M methylamine in THF (9.8 μL, 0.020 mmol) and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (8.7 mg, 0.020 mmol) in N,N-dimethylformamide (0.5 mL). The reaction mixture was stirred at r.t. for 3 h, and purified by RP-HPLC (pH=10) to afford the desired product. LCMS (M+H)+=461.0/463.0.
