Goal compound synthesis namely: Take the vanillic acid as outset raw material, obtains 4- hydroxyl - 3- anisole methyl formate with the methyl alcohol reflux conditions, then after the etherification, the nitration, the return to original state, the ring closure response obtains 6- methoxy - 7- animal pen oxygen radical kui zuo lin - 4- alkone, then passes through the chlorination, the substitution aniline, to escape responses again and so on animal pen oxygen radical, etherification to obtain the goal compound; The goal compound and the diethylamine had the amine substitution reaction to obtain TM1, namely 4- benzene amino - 6- methoxy - 7- [2- hydroxyl - 3-(N, N- two ethyl aminos) third oxygen radical] kui zuo lin; Through zuo has the etherification with the Austria niter to respond obtains TM2, namely 4- benzene amino - 6- methoxy - 7- [2- hydroxyl - 3-(2- methyl - 5- nitryl imidazole) third oxygen radical] kui zuo lin.
目标化合物的合成即:以香草酸为起始原料,与甲醇回流条件下得到4-羟基-3-甲氧基苯甲酸甲酯,然后经过醚化、硝化、还原、环合反应得到6-甲氧基-7-苄氧基喹唑啉-4-酮,然后再经氯化、取代苯胺、脱苄氧基、醚化等反应得到目标化合物;目标化合物与二乙胺发生胺取代反应得到了TM1,即4-苯氨基-6-甲氧基-7-[2-羟基-3-丙氧基]喹唑啉;通过与奥硝唑发生醚化反应得到TM2,即4-苯氨基-6-甲氧基-7-[2-羟基-3-(2-甲基-5-硝基咪唑)丙氧基]喹唑啉。

Next, regarding question two, because present uses the injection contraceptive the method to maintain this population the stability, moreover already did not have the individual to move away or the situation which poaches, for this reason we transform this populations stability to ask this population every years newborn baby quantity to subtract this year death individual the quantity differential value; Moreover from this population year quantity with this year the end of the years quantity differential value, when tends 0, namely thought that this community individual quantity is stable, thus the question stability problem transforms to ask simple targets optimization problems model building; Carries on using MATLAB to the model obtains, obtains, when did not consider when uncertainty factor influence must inject the medicine female animal quantity is 276 heads, but when had considered after twin and by duplicate injection these two uncertainty factor influence, obtains must inject the medicine female animal quantity is 352 heads, including 110 are by the duplicate injection.
其次,对于问题二由于现在采用注射避孕药的方法来维持该种群的稳定,而且已经没有个体被运走或被偷猎的情况,为此我们把该种群的稳定性转化为求该种群每年的新生幼仔的数量减去该年死亡个体的数量的差值;另外从该种群年头的数量与该年年底的数量的差值,当趋于0时,即认为该群落的个体数量是稳定的,从而把问题的稳定性问题转化为求单目标的最优化问题建立模型;利用MATLAB对模型进行求得,得出当不考虑不确定性因素影响时要注射药物的雌性动物数量为276头,而当考虑了双胞胎和被重复注射这两个不确定性因素影响后,得到要注射药物的雌性动物数量为352头,其中有110头是被重复注射的。
