Trifluoroacetic acid → 6-(cis-2-Aminocyclohexylamino)-5-chloro-2-(5-methylpyridin-3-ylamino)nicotinamide.hydrochloride

Participants

Reaction Steps

A mixture of tert-butyl cis-2-(3-chloro-5-(2-phenylpropan-2-ylaminocarbonyl)-6-(5-methylpyridin-3-ylamino)pyridin-2-ylamino)cyclohexylcarbamate (12 mg) and TFA (0.5 ml) was stirred at room temperature for 1 hour. The solvent was distilled away under reduced pressure (at 40° C. or less), ethyl acetate and 4N hydrogen chloride/1,4-dioxane (25 μl) were added, and the resultant was left at rest overnight at room temperature. Solid matter was collected by filtration, and a white solid of 6-(cis-2-aminocyclohexylamino)-5-chloro-2-(5-methylpyridin-3-ylamino)nicotinamide•hydrochloride (8 mg) was thus obtained.
