o-Cresol (2.16 g, 20 mmol) and sodium hydroxide (0.80 g, 20 mmol) were dissolved in water (50 ml) and to the solution was added 2-chloropyridimidine (2.30 g, 20 mmol) dissolved in THF (50 ml). The mixture was heated for 4 h. Water was added and the organic phase extracted with chloroform. The chloroform solution was dried over sodium sulfate; slow evaporation led to the formation of colorless crystals.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.95–0.98 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2–1.5U(C).In the absence of anomalous scatterers, 2119 Friedel pairs were merged. The
