Reaction Steps
The starting material can be obtained according to the procedure of A. B. Todd and F. Bergel, J. Chem. Soc. 1937, 366 from p-n-heptylbenzamie hydrochloride [prepared according to H. Schubert and H. Zaschke, J. prakt. Chem. 312, 494 (1970) from p-n-heptylbenzonitrile; melting point 126.0°-127.3° C[ and ethoxymethylenemalonic acid diethyl ester with sodium ethylate in ethanol and subsequent treatment of the obtained 2-(p-n-heptylphenyl)-4-hydroxy-5-primidinecarboxylic acid ethyl ester (melting point 184.7°-185.3° C) with phosphorus oxychloride. The melting point of 2(-p-n-heptylphenyl)-4-chloro-5-pyrimidinecarboxylic acid ethyl ester is 49.2°-49.8° C.
