실험 절차

To a solution of 5-(4-benzothiazol-2-ylmethyl-benzyl)-2,5-diaza-bicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (0.82 g, 1.9 mmol) in CH2Cl2 (19 mL) was added HCl (4.0 N in 1,4-dioxane, 7 mL) and the resulting white suspension was stirred at rt for 4 h. The reaction mixture was concentrated affording the title compound as a white solid (0.9 g, 100%).
