Hydrochloric Acid → HCID 53992726, compound

Participants

Reaction Steps

A mixture of 2-chloro-4-(4-chlorophenyl)-5-oxazolepropionic acid (1.43 g), thiophenol (0.54 ml), sodium methoxide-methanol solution (28%, 2.00 g) and methanol (15 ml) was stirred under reflux for 16 hours. Water was added to the reaction mixture, which was then acidified with 2 N hydrochloric acid. The crystals thus precipitated were collected by filtration to obtain 4-(4-chlorophenyl)-2-phenylthio-5-oxazolepropionic acid (1.60 g, 89%). This was recrystallized from methanol to give colorless needles. mp 156-157° C.
