実験手順

P-chloro cinnamic acid (1.84 g, 10 mM), 4-amino-1-(2,2-diethoxyethyl)-1H-pyrimidin-2-one (b, 3.00 g, 15 mM), 1-hydroxybenztriazolemonohydrate (2.30 g, 15 mM) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (2.90 g, 15 mM) were suspended in N,N-dimethylformamide (20 mL) and stirred at 70° C. for 5 hours. After the reaction mixture was cooled to room temperature, water (20 mL) was added and stirred at room temperature. The crystal precipitated from the reaction mixture was filtered to afford 2.48 g of the desired compound (E)-3-(4-chlorophenyl)-N-[1-(2,2-diethoxyethyl)-2-oxo-1,2-dihydropyrimidin-4-yl]-acrylamide (c) (yield 68%, colorless crystal).
