実験手順

In 10 ml of benzene, 180 mg of 6-chloro-4-(1-pyrazolyl)pyrimidine, 175 ml of phenol, and 152 mg of 1,8-diazabicyclo-(5,4,0)-7-undecene (DBU) were dissolved, and refluxed for 7 hours. This reaction solution was washed with water, and an organic fraction was dried over anhydrous sodium sulfate. The resulting extract was distilled to give a residue, and the residue was purified by alumina gel column chromatography using a mixture of n-hexane and ethyl acetate (2:1) to yield 175 mg 6-phenoxy-4-(1-pyrazolyl)pyrimidine, recrystallized from n-hexane, to give an acicular crystal having a melting point of 92.5°-93.5° C.,
