Participants

Reaction Steps

1-(2,6-Dichloro-4-nitrophenyl)-4-trifluoromethylpyrimidin-6-one (2.0 g) was added in one portion to a stirred suspension of stannous chloride (4.46 g) in concentrated aqueous hydrochloric acid (50 ml) at ambient temperature. After a period of 61/2 hours, the reaction mixture was poured into ice/water, made basic with aqueous sodium hydroxide solution, and extracted into ethyl acetate. The organic extracts were dried (magnesium sulphate), filtered, and evaporation of the solvent, under reduced pressure, gave 1-(4-amino-2,6-dichlorophenyl)-4-trifluoromethylpyrimidin-6-one as a yellow oil which solidified on standing (1.41 g). The compound showed:
