I made one with colorless clear solution but it turned yellow over time and don't know if it is good to use now or not :( chem potatohttps://www.blogger.com/profile/17128867834294506054noreply@blogger.comtag:blogger.com,1999:blog-51846086760422068.post-62372224647962834262014-03-20T15:42:07.238-07:002014-03-20T15:42:07.238-07:00Thanks!

For the second step, alkylation of PhSH, we didn’t conduct a systematic base screen and Cs2CO3 in CH3CN at rt worked very well. Other bases (such as NaH in THF) might also work but we didn’t tried that. High temperature should be avoided since we observed the formation of 2-(phenylthio)benzothiazole during this alkylation (in small amount). This route has not been published yet.
