実験手順

Methyl 4-(4-cyanophenyl)-6-methyl-2-(methylsulfanyl)-1-[3-(trifluoromethyl)-phenyl]-1,4-dihydro-5-pyrimidinecarboxylate Example 8; 9.51 g, 21.4 mmol) is dissolved in 175 ml THF/ethanol/water (10:5:1). Potassium hydroxide (3.59 g, 64.1 mmol) is added, and the reaction mixture is stirred overnight. The reaction mixture is diluted with 100 ml of water, and the aqueous phase is washed with diethyl ether. The resulting aqueous phase is acidified to pH 1 with hydrochloric acid, and the resulting precipitate is filtered off, dissolved in ethyl acetate and washed with water. After drying with sodium sulfate, the solvent is removed in vacuo to give the product.
