実験手順

To a solution of the product of Example 3, 4-ethylamino-2-methylsulfanyl-pyrimidine-5-carboxaldehyde (37.0 g, 0.19 mol) and 3,5-dimethoxyphenylacetonitrile (37.0 g, 0.21 mol) in DMF (300 mL) was added portionwise anhydrous K2CO3 (130 g) with stirring. The reaction mixture was heated overnight at 105–110° C. and filtered hot. The insoluble salts were washed with DMF (100 mL), and water was added to the warm filtrate until the solution just turned turbid. Crystals developed upon seeding or inducement (scratching with a glass rod). The product was collected by filtration, washed with 100 mL DMF/H2O (25:75), washed with water, and dried in vacuo to afford 50.5 g (76%) of the titled compound. mp 93–95° C.
