The title compound was prepared according to the method described for Example 3 using 5-(2-chloro-5-(3-fluoropyridin-2-yl)benzamido)-1-phenyl-1H-pyrazole-3-carboxylic acid (Example 105) and tert-butyl(2-aminoethyl)carbamate. The residue was dissolved in DCM (10 mL) and treated with 4M HCl in dioxane (5 mL) with stirring at room temperature for 4 hours. The reaction was concentrated in vacuo and eluted through an SCX-2 column using MeOH followed by 7N NH3 in MeOH; followed by reverse phase chromatography eluting with 5-95% MeCN (with 0.1% NH3) in water (with 0.1% NH3); followed by silica gel column chromatography eluting with 1-5% 7N NH3/MeOH in DCM and finally trituration with TBME.
