Hydrochloric Acid → 4-(3-bromophenyl)pyrimidin-2-amine

Participants

Reaction Steps

Combine 1-(3-bromo-phenyl)-3-dimethylamino-propanone (3.00 g, 11.8 mmol) and guanidinium chloride (1.12 g, 11.8 mmol), sodium ethoxide (5 mL, 21% wt solution in ethanol), absolute EtOH (24 mL) and heat to reflux overnight. Cool to room temperature and pour into 1% hydrochloric acid (200 mL). Extract with ethyl acetate, dry over sodium sulfate and condense to afford 4-(3-bromo-phenyl)-pyrimidin-2-ylamine (930 mg, 3.72 mmol) as a white solid. MS (m/z): 250.2 (M).
