Participants

Reaction Steps

The residue produced above was stirred, and 20 g. of methanesulfonic acid was added dropwise to it. After 4 hours of stirring, at room temperature, the solution was poured into 300 ml. of ice water, and the pH was adjusted with ammonium hydroxide to 7.5. A precipitate separated, which was collected and recrystallized from acetone to produce 2.5 g. of N-[5-(5-hydroxyphenyl)-1,3,4-thiadiazol-2-yl]-2,6-dimethoxybenzamide, m.p. above 260°.
