Hydrochloric Acid → 3-(4-Biphenylylthio)-2-hydroxypropionic acid

Participants

Reaction Steps

A mixture of ethyl 3-(4-biphenylylthio)lactate (0.093 g, 0.31 mmole), in NaOH (0.5 ml), water (2 ml) and tetrahydrofuran (1 ml) was stirred overnight at 25° C. The mixture was acidified (1 N HCl, 0.5 ml) and then extracted with methylene chloride (3×5 ml). The residue from evaporation of the methylene chloride was recrystallized from acetonitrile to yield 0.065 g of 3-(4-biphenylylthio)-2-hydroxypropionic acid, m.p. 175.5°-176° C.
