Versuchsvorschrift

12.6 g of 3-methyl-thiophene-2-carbaldehyde was dissolved in 150 mL of 95% alcohol, and 15.4 g of ammonium acetate was added at 45° C., then 20.8 g of malonate was added. The solution was refluxed for 16 hours, then cooled, and filtered to give a solid of 3-amino-3-(3-methyl-thiophene-2-yl)propionic acid.
