To a solution of tert-butyl (1-(4-((4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-chloropyrimidin-2-yl)amino)phenyl)ethyl)carbamate 24 (0.012 g, 0.022 mmol) in DCM (1 mL) was added trifluoroacetic acid (0.5 mL). The mixture was stirred at ambient temperature for 2 hours before the volatiles were removed in vacuo. The crude residue was loaded onto an SCX cartridge conditioned with methanol. The cartridge was washed with methanol and then 2 N ammonia in ethanol. The basic fractions were combined and the solvent removed in vacuo to give the title compound 24A as a colourless oil (0.009 g, 92%). LCMS-C: rt 4.41 min; m/z 436 [M+H]+.
