Versuchsvorschrift
Prepared according to Method M (Example 206) using (4-aminopyridin-2-yl)[1-(2-{[tert-butyl(dimethyl)silyl]oxy}-1,1-dimethylethyl)-1H-pyrrolo[3,2-c]pyridin-3-yl]methanone (Preparation 27) and 4-trifluoromethylphenylacetic acid at 70° C. The residue was purified over neutral alumina eluting with 50% EtOAc in hexane followed by acid deprotection using 10% HCl in dioxane at room temperature for 18 hours. The reaction was concentrated in vacuo and purified using preparative HPLC to afford the title compound.
