Reaction Steps

To a solution of 2-amino-5-bromopyridine (300 mg, 1.73 mmol) in DMF (1.5 mL) and proprionitrile (3.5 mL) under Argon were added DIPEA (613 μL, 3.71 mmol), tert-butyl acrylate (1.02 mL, 7.06 mmol), tri(o-tolyl)phosphine (106 mg, 0.35 mmol) and palladium acetate (39 mg, 0.17 mmol). The mixture was stirred at 100° C. for 20 h, then allowed to come back to room temperature, filtered through Celite pad and rinsed with EtOAc. The residue obtained after concentration was purified by flash chromatography (eluent: 95/5 DCM/MeOH) to give the title compound as an orange solid (380 mg, quantitative).
