A preferred form of the invention is a process comprising adding to a quantity of sodium which is covered with a hydrocarbon solvent boiling above 100°C., at least a chemically equivalent proportion of methyl, ethyl or a propyl alcohol, subsequently adding an approximately equivalent proportion of a dialkyl carbonate and of an alkyl phenylacetate, the alkyl groups in these two last-mentioned compounds being preferably the same as the alkyl radical of the above-mentioned lower aliphatic alcohol, heating the mixture to induce reaction and continually distilling out the alcohol formed from the reaction zone.
本发明的理想形式包括下面的工艺过程:把至少处于化学平衡的甲醇,乙醇或丙醇添加到覆盖着沸点超过一百摄氏度的碳氢化合物溶剂中,接着加入大约相同当量的二烷基碳酸酯和烷基乙酸苯酯,在刚才提到的化合物中,其烷基集团最好是和刚才提到的低级别脂肪族醇相同,然后加热反应混合物从而引导反应的进行,在反应区域通过连续蒸馏移除形成的醇类。

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。
