Participants

Reaction Conditions

Reaction Steps

In 30 ml of tetrahydrofuran was suspended 5.24 g of potassium t-butoxide, to which 2.63 g of phenylacetonitrile and 3.0 g of 4-chloro-6-methylthiopyrimidine, followed by stirring at 0° C. for 4 hours. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution and extracted three times with ethyl acetate. The organic layers were combined and washed with a saturated aqueous sodium chloride solution, and the combined organic layer was dried over anhydrous magnesium sulfate and then concentrated. The residue was subjected to silica gel column chromatography to give 3.67 g of 4-(α-cyanobenzyl)-6-methylthiopyrimidine.
