実験手順

To anhydrous Et2O (130 mL) at −78° C. was added tert-butyllithium (63.79 mL; 1.50 M; 95.68 mmol) (solution in pentane) which was followed by the slow addition of a solution of 1-[4-bromo-2-(methoxymethyl)phenyl]-2-methylpiperidine obtained in step 3 (12.97 g; 43.49 mmol) in anhydrous Et2O (20 mL). After 40 min, the reaction mixture was poured on an excess of freshly crushed dry ice and stirred for 30 min after which time it was diluted with Et2O/EtOAc (1:1), water (pH 4-5). The organic layers were combined, dried over MgSO4 and the solvents were removed under reduced pressure to give a yellow oil that was triturated in iPr2O and pentane, filtered off and washed with pentane to give the title compound as a beige powder. 1H NMR (CDCl3, 300 MHz) δ 8.22 (d, J=2.1 Hz, 1H), 8.00 (dd, J=8.3, 2.1 Hz, 1H), 7.17 (d, J=8.3 Hz, 1H), 4.60 (d, J=12.3 Hz, 1H), 4.55 (d, J=12.3 Hz, 1H), 3.46 (s, 3H), 3.17 (m, 1H), 3.02 (m, 1H), 2.63 (m, 1H), 1.88-1.65 (m, 4H), 1.55-1.40 (m, 2H), 0.88 (d, J=6.2 Hz, 3H). LC/MS (Method B): 264.1 (M+H)+.
