Procedure
A solution of 2-chloro-4-(2-fluoro-5-nitrophenyl)pyrimidine (800 mg, 3.2 mmol) in ethanol (300 ml) was reduced under 40 psi hydrogen with platinum(IV) oxide (100 mg) for 30 minutes then filtered to give a solution of 3-(2-chloropyrimidin-4-yl)-4-fluorophenylamine: MS (ES+) m/z 224 [M+H]+.
