Procedure

To a mixture of 1-{4-chloro-6-[2-(2,4-dichloro-phenyl)-ethylamino]-pyrimidin-2-yl}-ethane-1,2-diol (320 mg, 0.88 mmol) in MeOH (5 mL) and water (5 mL) is added sodium meta-periodate (567 mg, 2.65 mmol) and stirred for 16 hours before adding water (50 mL), and extracted thrice with EtOAc (30 mL). The organic extracts are combined and dried over magnesium sulfate, filtered and concentrated to afford 4-chloro-6-[2-(2,4-dichloro-phenyl)-ethylamino]-pyrimidine-2-carbaldehyde (270 mg, 93%) as a solid.
