To a solution of 2,6-dichloro-nicotinamide (1) (3 g, 15.7 mmol) in acetonitrile (anhydrous, 30 mL) were added 2-methyl-propan-1-ol (2) (1.22 g, 16.5 mmol) and NaH (0.42 g, 16.5 mmol). The reaction was kept at r.t. O/N. The suspension was filtered and the filtrate was concentrated in vacuo. The residue was purified by Biotage silica gel chromatography with 10%-80% EtOAc/hexanes gradient elution to afford 2.39 g (66% yield) of the title compound.
