Methyl 2-(6-amino-3-((1-benzyl-1H-pyrazole-4-carboxamido)methyl)-2-methylpyridin-4-yloxy)acetate (28 mg, 0.051 mmol) was dissolved in THF, EtOH, H2O 2:1:1 (5 ml), then LiOH (4.31 mg, 0.103 mmol) was added and the reaction mixture was stirred at rt over night. After adjusting the pH to 4, the reaction mixture was evaporated, co-evaporated with Toluene (4 times) then dried under HV to get the title compound which was used for the next step without further purification. HPLC/MS (Method B) Rtb=0.43 min, MS [M+H]+=396.3.
