Reaction Conditions:

with ammonia in water at 105; for 15 h;

Steps:

13.A
Example 13: (4S)-Λ/-Methyl-Λ/-(f5-(4-methyl-1-piperazinvnimidazo? .2-aloyridin-2- v?methyl)-3,4-dihvdro-2H-pyranof3,2-b1pyridin-4-arnine EPO A) 6-Fluoro-2-pyridinamine: A solution of 2,6-difluoropyridine (50 g, 434 mmol) in ammonium hydroxide (200 mL, 28.0- 30.0%) was heated at 1050C in a steel bomb for 15 hours. The reaction was cooled in an ice bath and the precipitate filtered, rinsed with cold water, and dried to yield 6-fluoro-2- pyridinamine (45.8 g, 94% yield) as a white solid. 1H-NMR (CDCI3): δ 7.53 (m, 1 H)1 6.36 (dd, 1 H), 6.26 (dd, 1 H), 4.56 (s, 2H).
