Abstract
Derivatives of 2-(1-pyrazolyl)-4(3H)-pyrimidinone and 2-(1-pyrazolyl)purine were obtained, and their UV and IR spectra were studied. It is shown that alkyl derivatives of hypoxanthine and 6-chloro- and 6-ethoxypurine exist in the 7H form, which is stabilized by an intramolecular hydrogen bond.
