p-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 was extracted with chloroform. The chloroform solution was dried over sodium sulfate; slow evaporation led to the formation of colorless crystals.
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).Data collection: APEX2 (Bruker, 2008); cell
