Procedure

TFA (1 mL) was added to a solution of tert-butyl 4-(5-((4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-chloropyrimidin-2-yl)amino)pyridin-2-yl)piperidine-1-carboxylate A19 (79.0 mg, 0.137 mmol) in DCM (5 mL) and stirred for 16 hours. The volatiles were removed in vacuo and the resultant residue loaded onto an 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 and the solvent was removed in vacuo to give the title compound 15 as a white solid (50 mg, 77%). 1H NMR (400 MHz, d4-MeOD) δ 8.74 (s, 1H), 8.36 (s, 1H), 8.21 (dd, J=8.6, 2.7 Hz, 1H), 7.45-7.22 (m, 5H), 3.30-3.17 (m, 6H), 2.95-2.80 (m, 3H), 1.99-1.96 (m, 2H), 1.86-1.76 (m, 2H), 1.64-1.63 (m, 2H), 1.19-1.07 (m, 2H). LCMS-C: rt 4.17 min; m/z 477.1 [M+H]+.
