Versuchsvorschrift

To a mixture of trans-tert-butyl 1-benzyloctahydro-6H-pyrido[3,4-b][1,4]oxazine-6-carboxylate (82 g, 246 mmol) in EtOAc (500 mL) at 0° C. was added HCl in EtOAc (1500 mL, 4 M) dropwise. The reaction was stirred at room temperature for 2 hours. The mixture was concentrated to afford 1-benzyloctahydro-1H-pyrido[3,4-b][1,4]oxazine as a mixture of trans diastereomers.
