Pre Step A
5-Fluoro-4-pyrimidinamine
A mixture of 4-chloro-5-fluoropyrimidine (200 mg, 1.509 mmol) and ammonia (3.3 ml, 45.3 mmol) in methanol (580 μl) was heated to 110° C. via a microwave reactor for 30 min.
The reaction was filtered and the solid was dried to give 5-fluoro-4-pyrimidinamine (100 mg, 0.875 mmol, 58% yield) as a white solid. MS (ES+) m/z 114.1 (MH+).
