Reaction Steps

To a heterogeneous mixture of ethyl 3-(4-(2-carbamoylpyridin-4-yloxy)-2,5-difluorophenylamino)-3-oxopropanoate (305 mg, 0.80 mmol) in MeOH (8 mL) was added aqueous 1 M NaOH (1.70 mL, 1.70 mmol). After one hour of stirring, the mixture was acidified with aqueous 1N HCl (5 mL). The reaction was extracted with EtOAc before the combined organic layers were dried (MgSO4), filtered and concentrated in vacuo to afford the title compound (317 mg) which was used without further purification. HRMS(ESI+), 352.0745 (M+H)+ calcd., 352.0752 (M+H)+ found.
