Allylamine → Ethyl 4-(allylamino)-2-phenyl-5-pyrimidinecarboxylate

Participants

Reaction Steps

A mixture of 5 g. (0.019 mole) of 4-chloro-2-phenyl-5-pyrimidine carboxylic acid ethyl ester and 2.2 g. (0.038 mole) of allylamine in 150 ml. of ethanol was refluxed 3 hours. At this point, the solution was concentrated to 30 ml. and chilled. A yellow crystalline solid formed and was filtered off to give 4-(2-propenylamino)-2-phenyl-5-pyrimidine carboxylic acid ethyl ester--m.p. 49°-54° C. This compound was used in the next step directly without further purification.
