Reaction Steps

To a solution of ethyl 2-aminoisonicotinate (500 mg, 3.01 mmol) in DMF (10 ml) is added triethylamine (1.26 ml, 9.03 mmol) and then isopropyl isocyanate (512 mg, 6.02 mmol). The reaction mixture is heated in a microwave at 140° C. for 2 hours. The reaction mixture is diluted with EtOAc, washed with water (×5), brine, dried (MgSO4) and concentrated in vacuo. Chromatography (SiO2, MeOH/DCM) affords 2-(3-Isopropyl-ureido)-isonicotinic acid ethyl ester; [M+H]+ 252
