The ammonia was evaporated under decreasing pressure, and the precipitate was filtered off and the liquid was poured into hot saturated picric acid solution to get picrate with a yield of 85.0%. The optimum process starting from imidazole-4,5-dicarboxylic acid was: imidazole-4,5-dicarboxylic acid in acetic anhydride was refluxed to get imidazole-4-carboxylic acid, and the product was esterification in ethanol with a catalyzer of concentrated sulfuric acid to get ethyl imidazole-4-carboxylate, at last the compound above was reduced by LiAlH4 in ether at room temperature to get the target compound, the total yield of this route was 49.6%.

The catalysts such as tetraphenyl tin,aluminium isopropoxide and boron trifluoride etherate complex were used to catalyze the copolymerization.In addition,the copolyester can be given by copolycondensation after monomers were hydrolyzed by phosphoric acid.Boron trifluoride etherate complex was chosen as the catalyst because the catalytic activity was the best among the catalysts.
由于γ-戊内酯为五元环结构，难以进行开环聚合，因此分别考察了四苯基锡、异丙醇铝、三氟化硼乙醚络合物等催化剂，以及以磷酸为催化剂的水解缩聚反应，结果发现三氟化硼乙醚络合物的催化活性最高，因此选择三氟化硼乙醚为本体开环聚合的催化剂。

The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60-120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever.
