Participants

Reaction Steps

2-(1-Imidazolyl)ethanethiolacetate can be prepared by a method similar to that described in Example 11 for the preparation of the starting material, but starting from 2-(1-imidazolyl)ethanol (15 g), triphenylphosphine (70.2 g), diisopropyl azodicarboxylate (55.8 cc) and thiolacetic acid (21 cc). After purification by "flash" chromatography [eluent: methylene chloride (1500 c), followed by ethyl acetate-methanol (80-20 by volume)], 100-cc fractions being collected, and concentrating fractions 21 to 35 to dryness under reduced pressure (2.7 kPa) at 30° C., 2-(1-imidazolyl)ethylthioacetate (21.14 g) is obtained in the form of an orange-yellow oil which is used without further purification.
