这是合成的方法,可以参考看下。谢谢了。  As 6-mercaptonicotinamide(6-MNA)is commercially not available,it was synthesized according a method developed by Forrest et al.[16].In brief,6-chloronicotinamide and thiourea were suspended in ethanol and refluxed for 6 h.Over time,the suspension turned light yellow.The reaction mixture was allowed to cool down to room temperature and stirred over night.The resulting salt S-(5-carbamyl-2-pyridyl)thiouronium chloride was then separated by filtration and brought to dryness.The dry thiouronium salt was decomposed through addition of alkaline solution and stirred for 45 min at room temperature.Acetic acid was added to adjust the pH to 4,whereby the light yellow suspension turned to a dark yellow color.The resulting 6-MNA was isolated by?ltration,washed with water and brought to dryness.

6 - 巯基烟酰胺,根据谷歌翻译结果,综合合成反应,单词中间应该有空格,如下:6-mercapto nicotinamide
