Reaction Steps

4,4-Dimethyl-2-pyrrolidinone (2.52 g, 22.3 mmol) was added to a mixture of concentrated HCl (50 mL) and water (50 mL) and the resulting mixture was refluxed at 120° C. for 20 hours. After it was cooled to room temperature, the mixture was washed twice with dichloromethane. The aqueous layer was evaporated to give 4-amino-3,3-dimethyl-butyric acid hydrochloride compound 55-B (3.4 g) as a white solid.
