Potassium Hydroxide → 5-(2,4-Dimethylphenyl)-2-(dipropylamino)-3-methylpyrimidin-4(3H)-one

Participants

Reaction Steps

To a solution containing 0.2 g (0.74 mmol) of 5-(2,4-dimethylphenyl)-3-methyl-2-propylaminopyrimidin-4(3H)-one in 5 ml of tetrahydrofuran under a nitrogen atmosphere was added 0.12 g (2.2 mmol) of potassium hydroxide followed by 0.38 g (2.2 mmol) of 1-iodopropane. The reaction was allowed to stir at room temperature for 12 h, diluted with ethyl acetate and washed with saturated sodium bicarbonate. The organic phase was dried over magnesium sulfate. Filtration, removal of solvent and purification of the residue via Biotage chromatography eluting with 30% ethyl acetate/dichloromethane gave 0.15 g (65%) of product.
