Procedure

To a stirred solution of (S,S)-5-{2-[4-(benzothiazol-2-yloxy)-phenoxy]-ethyl}-2,5-diaza-bicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (1.7 g, 3.6 mmol) in CH2Cl2 (15 mL) was added trifluoroacetic acid (5 mL, 65 mmol). The resulting solution was stirred at rt for 8.5 h. The solution was concentrated to provide the title compound as an oil and used as a crude compound. MS (ESI): mass calcd. for C20H21N3O2S, 367.14; m/z found, 368.2 [M+H]+. 1H NMR (400 MHz, CDCl3, mixture of rotamers): 7.73 (d, J=7.9 Hz, 1H), 7.65 (d, J=7.9 Hz, 1H), 7.38 (t, J=7.7 Hz, 1H), 7.29-7.23 (m, 3H), 6.99-6.91 (m, 2H), 4.13-4.01 (m, 2H), 3.56-3.39 (m, 2H), 3.35-3.32 (m, 1H), 3.20 (d, J=10.4 Hz, 0.5H), 3.09 (dd, J=9.7, 2.4 Hz, 0.5H), 3.06-2.82 (m, 3.5H), 2.76-2.67 (m, 1H), 2.50 (dd, J=9.6, 1.1 Hz, 0.5H), 1.88-1.57 (m, 2H).
