Reaction Steps

A solution of 3.1 g (8.01 mmol) of 3-[(7R,9aS)-2-BOC-2,3,4,6,7,8,9,9a-octahydro-1H-pyrido[1,2-a]-pyrazin-7-ylmethyl]-3H-benzooxazol-2-one in 40 mL of chloroform was stirred with excess HCl (g) in ethyl ether for 2 h at ambient temperature. The solvent was evaporated to give 2.3 g (100%) of the title compound dihydrochloride which was used for subsequent reactions without further purification.
