Reaction Steps

A solution of 5-cyano-2-fluoro-3-methylpyridine (Molekula, 400 mg; 2.94 mmol) in 1-butanol (1 mL), 2-methylpyrrolidine (Acros, 300 mg; 3.53 mmol) and DIEA (1.52 mL; 8.82 mmol) was heated at 90° C. for 18 hours. Reaction mixture was partitioned between EtOAc and water and washed with water to give the title compound as a yellow oil (600 mg, quantitative). HPLC (Method A) Rt 1.99 min (Purity: 96.1%). LC/MS (Method B): 202.1 (M+H)+.
