The butenenitrile above reacted with hydroxylamine hydrochloride to give 5- amino -3- methyl-5-isoxazole which chloridized with N-chlorosuccinimide to give 5- amino 4-chlor.
本文以乙腈为原料先二聚生成3-氨基-2-丁烯腈,再与盐酸羟胺反应生成5-氨基-3-甲基-异恶唑,接着用N-氯代丁二酰亚胺氯化生成5-氨基-4-氯-3-甲基-异恶唑,然后与2-甲氧羰基-3-噻吩磺酰氯反应合成3-(4-氯-3-甲基-5-异恶唑磺酰胺基)-2-噻吩甲酸;以4-甲基-邻苯二酚为原料与二氯甲烷反应生成3,4-亚甲二氧基-甲苯,再氯甲基化得到3,4-亚甲二氧基-6-甲基苄氯;以上两种合成的原料通过Weinreb酮合成法制得Sitaxsentan,最后用饱和碳酸氢钠溶液处理得到Sitaxsentan钠盐。
