ethyl 4-amino-3,3-dimethylbutanoate;hydrochloride

Conditions: temp:85.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Acetyl chloride (31 ml) was added dropwise over a time period of 5 minutes to ethanol (180 ml) while stirring and cooling in ice water bath. After additional 5 minutes, the obtained solution was added to a solution of 4-amino-3,3-dimethyl-butyric acid hydrochloride (30.07 grams, 180 mmol) in ethanol (20 ml). The mixture was refluxed at 85° C. for 16 hours, and the solvent was removed under reduced pressure to give to 4-amino-3,3-dimethyl-butyric acid ethyl ester hydrochloride (33.11 grams, 94% yield) as oil. the solvent was removed under reduced pressure
