実験手順
A solution of 0.44 g (1.2 mmol) of (7S,9aR)-2-BOC-7-(4-fluorophenoxy)methyl-2,3,4,6,7,8,9,9a-octahydro-1H-pyrido[1,2-a]pyrazine in 25 mL of chloroform was treated with excess HCl(g) in ethyl ether and stirred at ambient temperature for 2 h. The solvent was evaporated to give 0.40 g of title compound as the dihydrochloride salt which was used for subsequent reactions without purification.
