Reaction Steps

Method F2 was used with 8-(4-amino-3-fluorophenoxy)pyrido[2,3-b]pyrazin-3(4H)-one (30.6 mg, 0.112 mmol) and a 60.6 mM solution of phenyl 2-(pyridin-3-yloxy)-5-(trifluoromethyl)phenylcarbamate (1.6 ml, 0.097 mmol). After 40 h, the mixture was evaporated onto silica gel, loaded onto a Biotage 12+M column, which was eluted with 40%-100% EtOAc in DCM. Yield: 4 mg (7%).
