Reaction Steps
To a solution of 2,4-dichloro-5-fluoro-pyrimidine (1.84 g, 11.00 mmol) and tert-butylhydrazine hydrochloride (1.25 g, 10.00 mmol) in THF (50 mL) and EtOH (5 mL) was added triethylamine (4.18 mL, 30.00 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was filtered to remove triethylamine HCl salt and the filtrate concentrated in vacuo. The resulting residue was purified by silica gel chromatography (EtOAc/Hexanes) to afford 1.7 g of the desired product: 1H NMR (400 MHz, CDCl3) δ 7.82 (d, J=2.8 Hz, 1H), 6.47 (s, 1H), 4.60 (d, J=5.8 Hz, 1H), 1.09 (s, 9H). LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, Retention Time=2.19 minutes (M+H) 218.81.
