Reaction Steps

The HCl salt was prepared as follows. To a 50 mL RBF under argon was charged with (+/−)-(2-Methoxy-2-phenyl-cyclohexylmethyl)-dimethyl-amine (0.251 g, 1.01 mmol). To the flask was added 5 mL of dry MTBE. 2N HCl (0.80 mL, 1.60 mmol) was added dropwise at room temperature. After stirring for 1 hour at room temperature, the white precipitate was filtered in vacuo to provide 0.22 g (77%) of HCl salt. 1H NMR (CDCl3) 1.45-1.97 (m, 7H), 2.10 (s, 3H), 2.14 (m, 1H), 2.38 (d, J=11.3 Hz, 1H), 2.54 (s, 3H), 2.73 (d, J=12.4 Hz, 1H), 2.86 (dd, J=7.7, 12.8 Hz, 1H), 3.22 (s, 3H), 7.28 (m, 3H), 7.39 (m, 2H). 13C NMR (75 MHz, CDCl3) 22.8, 25.6, 28.2, 32.5, 42.4, 44.8, 45.7, 50.7, 61.3, 81.4, 127.9, 128.6, 129.9, 143.5. Mass spectrum (m/e) 249.0 (M+).
