4-[3-(2-Phenyl-pyridin-4-yl)-imidazo[1,2-a]pyridin-7-yl]-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (Ex. 1.103) (1.0 eq, 0.2 mmol, 90 mg) is dissolved in dioxane/MeOH (1 ml, 1 ml) and HCl (4M in dioxane, 10.0 eq, 2.0 mmol, 0.5 ml) is added. The reaction is stirred at room temperature for 16 h. The solvent is removed in vacuo to yield 3-(2-phenyl-pyridin-4-yl)-7-(1,2,3,6-tetrahydro-pyridin-4-yl)-imidazo[1,2-a]pyridine as a yellow solid; [M+H]+=353
