Reaction Steps

TFA (1 mL) was added to a solution of tert-butyl 4-(4-((4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-chloropyrimidin-2-yl)amino)-1H-pyrazol-1-yl)piperidine-1-carboxylate A20 (0.021 g, 0.037 mmol) in DCM (5 mL) and the mixture was stirred for 16 hours. The volatiles were removed in vacuo and the resultant residue loaded onto a SCX cartridge (5 g). The cartridge was washed with MeOH (100 mL) and then with 5% NH4OH in MeOH (100 mL). The basic fractions were combined, the solvent was removed in vacuo and the resultant residue purified by prep-LCMS to give the title compound 17 as a yellow solid (3.6 mg, 21%). LCMS-B: rt 4.711 min; m/z 466.2 [M+H]+.
