Preparation method of 1,4-dihydroxyl,-1,2,4,5-tetrapyridylcyclohexane

The invention discloses a preparation method of 1,4-dihydroxyl-1,2,4,5-tetrapyridylcyclohexane, belonging to the field of organic synthesis. The invention aims to provide a new method featuring short synthesis time and low raw material cost. The key pints of the technical scheme are as follows: terephthalic acid, sodium hydroxide, copper nitrate and 1,3-bis(4-pyridyl) propane are served as the raw materials, the raw materials are subject to hydro-thermal reaction at a temperature of 170 DEG C-180 DEG C for 36-60 hours, and then extraction and separation are carried out to obtain 1,4-dyhydroxy-1,2,4,5-tetrapyridylcyclohexane. The method of the invention can noticeably reduce preparation cost, shorten reaction period, the obtained product has the characteristic of high purity and the invention solves the defects that the preparation cost is high, reaction period is long and the method is difficult to be applied to the field of coordination polymer function materials.
