Versuchsvorschrift

To a solution of 2,4-dichloro-6-propyl-pyrimidine (0.15 g) and 4-(3-trifluoromethoxy-phenyl)-1H-imidazole (0.2 g) in N,N-dimethylformamide (10 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (0.18 mL). After stirring at room temperature overnight, the solution was taken up in water and extracted three times with ethyl acetate. The ethyl acetate layers were combined washed twice with brine, dried over magnesium sulfate, and the volatiles were removed in vacuo. The resulting oil was purified on silica gel using 20% ethyl acetate/hexanes as the mobile phase to yield 4-chloro-6-propyl-2-[4-(3-trifluoromethoxyphenyl)-imidazol-1-yl]-pyrimidine (72.5 mg, first eluting regioisomer, ESI-MS (m/z) 383.3/385.2 [M+H]+, and 2-chloro-4-propyl-6-[4-(3-trifluoromethoxyphenyl)-imidazol-1-yl]-pyrimidine (88.4 mg, second eluting regioisomer).
