実験手順
A solution of ethyl 1,6-dihydro-6-oxo-2-(2-ethoxyphenyl)pyrimidine-5-carboxylate (2 g., 6.9 mmole) in 1N NaOH (20 ml., 20 mmole) was heated at reflux for 10 minutes. The solution was cooled and acidified with 6N HCl to yield the title product (1.8 g., m.p. 168°-184°). Recrystallization from acetonitrile gave 1.2 g. of colorless crystals, m.p. 186°-188°.
