Reaction Steps

5-Fluoro-4,6-dichloro-2-pyrimidineamine (4) (204 mg, 1 mmol) and ammonium hydroxide (15 ml) were charged to a sealed tube and ethanol (1.5 ml) added. The tube was heated at 100° C. for 24 hours. The solution was concentrated. The residue was absorbed on silica gel and chromatographed (elution with ethyl acetate), yielding (5) as a white powder (118 mg, 65%): MS (70 eV, EI) m/z (relative intensity) 162 (M+, 100), 43 (92), 164 (33), 127 (29), 135 (16). Exact Mass Calcd for C4H4N4ClF: 162.0108. Found: 162.0100.
