55 °C

There were added to a mixture of 200 grams of 2-benzoyl-3-nitro-6-chloropyridine and 1 liter of ethanol with stirring 120 grams of sodium hydrogen sulfide monohydrate in portions. The temperature increased to 55° C. After the addition boiling was carried out for one hour at reflux, the solution filtered and acidified with glacial acetic acid. Upon addition of water, the reaction product crystallized. It was dissolved in dilute sodium hydroxide solution, the solution filtered, and the mercapto compound again precipitated with glacial acetic acid.
