Sodium hydride → 2-Methyl-5-[6-(4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-quinoxaline

Participants

Reaction Steps

The title compound was prepared analogous to the procedure in Example 29 using 4-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidine, (Example 2(a), Method A), (0.20 g, 0.77 mmol), 2-methyl-quinoxalin-5-ol (0.14 g, 0.85 mmol, J. Med. Chem, 1988, 41, 4062.) DMF (3 mL), and a 60% dispersion of sodium hydride in mineral oil (0.040 g, 1.0 mmol, Aldrich). Purification by flash chromatography (0→75% EtOAc/hexanes) gave the title compound as an ivory powder. Mp: 135–141° C., MS (ESI, pos. ion) m/z: 383 (M+1).
