Acetone → 6-chloro-N-(3-(trifluoromethyl)phenyl)pyrimidin-4-amine

Participants

Reaction Steps

A stirred mixture of 4,6-dichloropyrimidine (18.6 g, 125 mmol), 3-aminobenzotrifluoride (16.5 mL, 133 mmol), acetone (60 mL) and H2O (90 mL) is kept at reflux for 3 h. Acetone is removed in vacuo, the remaining aqueous layer is basified with conc. aqueous ammonia solution and extracted with ethyl acetate. The organic extract is dried over Na2SO4 and evaporated. The residue is suspended in a small amount of acetone, filtered and the filter cake dried in vacuo to afford the title compound.
