A mixture of ethyl 4-thiazolecarboxylate (24.49 g) and monoethanolamine (28.0 ml) was heated at 100° C. with stirring for 1 hour 20 minutes. After being cooled, the mixture was subjected to column chromatography on silica gel (245 g) and eluted with chloroform. The fractions containing the objective compound were combined and concentrated under reduced pressure to give a light brown oil of N-(2-hydroxyethyl)-4-thiazolecarboxamide (25.93 g).
