with ammonium hydroxide in ethanol at 85; for 16 h;
Steps:
2.1.A 3-Aminocyclopent-2-en-1-one
3-Aminocyclopent-2-en-1-one
27.5 ml of aqueous ammonia solution (28%) were added to a solution of 5.5 g (43.6 mmol) of 3-ethoxy-2-cyclopenten-1-one in 55 ml of ethanol, and the mixture was stirred at 85° C. for 16 h.
After cooling to RT, the reaction mixture was concentrated under reduced pressure and dried. Yield: 4.2 g (quant.)
GC/MS [Method 5]: Rt=4.78 min; MS (EI): m/z=97.
