HCl solution in 1,4-Dioxane (4.0 M, 1.0 ml, 4.0 mmol) was added to a stirred solution of (R)-tert-butyl 4-(4-(5-chloropyridin-3-yl)-3-((trans-4-methylcyclohexyl)methyl)-6-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)-3H-imidazo[4,5-c]pyridin-2-yl)-3-methylpiperazine-1-carboxylate (164 mg, 0.263 mmol) in 1,4-dioxane (1 ml) at room temperature, and the mixture was stirred at room temperature overnight. The solvent was evaporated under reduced pressure to give 3-(4-(5-chloropyridin-3-yl)-3-((trans-4-methylcyclohexyl)methyl)-2-((R)-2-methylpiperazin-1-yl)-3H-imidazo[4,5-c]pyridin-6-yl)-1,2,4-oxadiazol-5(4H)-one (HCl salt). MS ESI calc'd. for C26H31ClN8O2 [M+H]+ 523. found 523.
