Ty. Rho et Yf. Abuh, ONE-POT SYNTHESIS OF PYRIMIDINE-5-CARBOXALDEHYDE AND ETHYL PYRIMIDINE-5-CARBOXYLATE BY UTILIZING PYRIMIDIN-5-YL-LITHIUM, Synthetic communications, 24(2), 1994, pp. 253-256
Pyrimidine-5-carboxaldehyde was prepared in a one-pot reaction from 5-
bromo-pyrimidine via metal halogen exchange. Pyrimidin-5-yl-lithium re
acted with formate ester and ethyl cyanoformate, forming respectively
the aldehyde and carboxy ethyl ester.
