Versuchsvorschrift
N-Acetylguanidine (1.516 g, 15 mmol, 3 equivalents, commercially available Aldrich) was added to 1-chloropropan-2-one (0.462 g, 5 mmol, 1 equiv) in acetonitrile (30 ml). The reaction mixture was heated to reflux for 12 hours under argon. Upon cooling, the reaction mixture was evaporated to dryness and the isolated residue was washed with water, filtered and air-dried to give 0.324 g N-(4-methyl-1H-imidazol-2-yl)acetamide. 1H-NMR (400 MHz, DMSO-d6): δ 13.3 (bs, 1H), 10.29 (bs, 1H), 6.80 (s, 1H), 2.27 (s, 3H), 2.02 (s, 3).
