Versuchsvorschrift

A mixture of 10 g. (0.038 mole) of 4-chloro-2-phenyl-5-pyrimidine carboxylic acid ethyl ester and 7.1 g. (0.076 mole) of aniline in 200 ml. of ethanol was refluxed for 3 hours. Upon cooling a yellow solid precipitated from the solution. This was filtered off and rinsed with ethanol to give 4-anilino-2-phenyl-5-pyrimidine carboxylic acid ethyl ester, m.p. 98°-100° C. No further purification was done and the product was used directly in the next step.
