Reaction Steps
To a solution of tert-butyl 1-(4-(4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-ylamino)phenyl)ethylcarbamate 70 (0.11 g, 0.19 mmol) in DCM (4 mL) was added trifluoroacetic acid (2 mL). The mixture was stirred at ambient temperature for 16 hours before the volatiles were removed in vacuo. The crude residue was purified using an SCX conditioned with MeOH, product was eluted off with 2 M ammonia in EtOH) to give the title compound 70A as a cream solid (0.073 g, 81%). LCMS-C: rt 4.48 min; m/z 470 [M+H]+.
