In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Dimethylpyridin-4-ylamine-catalysed alcoholysis of 2-amino-N,N,N-trimethyl-9H-purine-6-ylammonium chloride: An effective route to O6-substituted guanine derivatives from alcohols with poor nucleophilicity, published in 2002-03-31, which mentions a compound: 39891-05-9, Name is (6-Fluoropyridin-3-yl)methanol, Molecular C6H6FNO, Formula: C6H6FNO.
Dimethylpyridin-4-ylamine (DMAP)-catalyzed reactions of 2-amino-N,N,N-trimethyl-9H-purine-6-ylammonium chloride with fluoropyridine methoxides and various other alkoxides in DMSO at 60 °C gave the corresponding coupling products in moderate to good yields between 20-87%. Under these reaction conditions, fluorinated O6-substituted Guanine derivatives have been synthesized which could not be obtained via known analogous literature procedures. The resp. yields of known O6-substituted guanine derivatives could be significantly improved by using this method. The efficient use of DMAP as an excellent nucleophilic catalyst in the syntheses of O6-substituted Guanine derivatives has thus been demonstrated.
