Procedure
Cool a solution of 3-(2-acetylamino-1-hydroxy-3-phenylpropyl)-7-methoxymethyl-2-azabicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (Isomer 1) (0.044 g, 0.102 mmol) in tetrahydrofuran (1 mL) and add a solution of hydrochloric acid (2.0 mL, 4 M in 1,4-dioxane). Stir the mixture for 5 h at room temperature, concentrate and purify (silica gel chromatography, eluting with 2 M ammonia in 5:95 to 10:90 methanol:dichloromethane) to give the title compound after treatment with the same equivalent of hydrochloric acid in diethyl ether (16 mg, 43%).
