Participants

Reaction Steps

A mixture of 2-amino-1,3-thiazole, which can be represented as 2-imino-2,3-dihydro-1,3-thiazole, (36.3 g.), glyoxylic acid hydrate (50 g.) and 1N sodium hydroxide (543 ml.) was stirred for 1.5 hours at 90° to 93° C. After the reaction, the reaction mixture was treated with an activated charcoal and then adjusted to pH 3. The mixture was allowed to stand overnight under ice-cooling. The precipitates were collected by filtration, washed with water and then dried to give 2-hydroxy-2-(2-amino-1,3-thiazol-5-yl)acetic acid hydrate, which can be represented as 2-hydroxy-2-(2-imino-2,3-dihydro-1,3-thiazol-5-yl)acetic acid hydrate (48.1 g.), mp. 140° to 200° C. (dec.).
