Synthetic compounds have trimethoprim category to improve processes, solid sulphur thiourea, urea, hydrochloric acid guanidine into ethanol sodium solution, heated to make it dissolved, and then Dijia clean Yisuanyi by Central compounds containing trimethoprim. Savings of raw materials, increased proction rates; Traube condensation reaction was further through a series of Piaoling compounds, some of which have anti-virus, anti-tumor effect. After numerous experiments found room temperature 2,4,5- three amino -6- hydroxy trimethoprim with Shuiyang aldehyde, formaldehyde neighbors chlorobenzene, Chenopodium album Lo aldehyde reaction, 2- hydrosulfuryl base -6- hydroxy -4,5- two amino trimethoprim with Shuiyang aldehyde reaction synthetic four seats husband alkali, according to responses from the end of the structure, nature and conditions of reaction testing infrared spectral results projections generated compounds may structure.

Synthesize a craft to carry on an improvement towards there hasing been the 啶 compound of 嘧 , join the solid sulphur 脲 , urea, hydrochloric acid 胍 to the ether sodium aqua, heat to make it fuse as far as possible, then the drop adds the cyanotype acetic acid B ester, being contained the 嘧啶 wreath compound.Saved raw material and raised to proce a rate;Further match reaction to get a series of 嘌 purine compound through a Traube 缩 , among them some have virussafe, anti- tumor result.Was discovered by many experiments the normal temperature descends 2, 4, 5-3 ammonia 基s-6-the 羟基嘧啶 can and water 醛 , 邻 chlorine benzene formaldehyde, the 藜芦醛 reaction, 2-巯基 -6-羟基 -4, 5-2 ammonia 基嘧啶s can with water 醛 respond, synthesize four seat man alkali, according to respond bottom thing of structure, property and respond the condition combine a red and outside spectrum examination a result, calculating the possible structure of born compound.
