The synthetic route is as follows., Formula: C5H11BrO2
Example 7 (+-)-3-{1-[2-(2-Methoxyethoxy)ethyl]-trans-3,4-dimethylpiperidinyl}phenol To a solution of (+-)-3-(trans-3,4-dimethylpiperidinyl)phenol (60 mg, 0.29 mmol) in N,N-dimethylformamide (5.0 mL) at room temperature was added sodium hydrogencarbonate (27 mg, 0.32 mmol), and 1-bromo-2-(2-methoxyethoxy)ethane (59 mg, 0.32 mmol). The solution was heated at 120 C. for 1 hour, cooled and then water (10 mL) was added. The aqueous layer was extracted with ethyl acetate and the combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to give a crude oil. This was purified by preparative HPLC on a Dynamax column, 42*250 mm; flow 8.0 mL min-1; employing U.V. detection at 275 nm; eluant gradient of acetonitrile:0.05 M aqueous ammonium acetate solution (90:10 to 10:90) to afford the title compound (71 mg, 80%) as its acetate salt. 1H-NMR (data for the acetate salt): 0.82 (d, 3H), 1.35 (s, 3H), 1.72 (m, 1H), 2.03-2.10 (m, 4H), 2.38 (m, 1H), 2.81-3.13 (m, 6H), 3.40 (s, 3H), 3.50-3.63 (m, 4H), 3.70-3.78 (m, 2H), 6.68 (m, 1H), 6.81-6.82 (m, 2H), 7.18 (t, 1H). MS (TSI+): m/z [MH+] 308.3; C18H29NO3+H requires 308.2.
