Procedure

A suspension of 1-bromo-2,3-butanedione (47 g) and N-[(thiocarbamoyl)methyl]acetamide (30 g) in acetone (600 ml) was refluxed for 3 hours. The resulting precipitate was collected by filtration to afford 4-acetyl-2-(acetylaminomethyl)thiazole (41.8 g).

Workup

  1. temperaturewas refluxed for 3 hours
  2. filtrationThe resulting precipitate was collected by filtration
