1-[4-溴-2-(甲氧基甲基)苯基]-2-甲基吡咯烷

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 1-[4-Bromo-2-(methoxymethyl)phenyl]-2-methylpyrrolidine (16.5 g, 58 mmol) in anhydrous THF (160 mL) was added n-butyl lithium in drops at −78° C. After 3 hours at −78° C., the reaction mixture was poured onto crushed dry-ice (100 g). Once the excess carbon dioxide was escaped, the reaction mixture was evaporated, and then acidified with 1.5 N HCl. The precipitate was filtered off and washed with pet ether to afford title compound as a solid. LC/MS (Method B): 249.9 (M+H)+. 1H NMR (DMSO-d6, 400 MHz) δ 12.4 (1H, brs), 7.84 (1H, s), 7.70 (1H, d), 6.85 (1H, d), 4.32-4.42 (2H, m), 3.59-3.87 (1H, m), 3.56 (1H, m), 3.29 (3H, s), 3.13 (1H, m), 2.14 (1H, m), 1.89 (1H, m), 1.74 (1H, m), 1.55 (1H, m), 0.99 (3H, d). the reaction mixture was poured the reaction mixture was evaporated The precipitate was filtered off washed with pet ether

实验步骤: To a solution of sodium hydride (2.84 g, 119 mmol) in anhydrous DMF (80 mL) was added a solution of [5-Bromo-2-(2-methylpyrrolidin-1-yl)phenyl]methanol (16 g, 59.2 mmol) in DMF (50 mL) drop wise at 0° C. After 30 minutes, methyl iodide (7.3 mL, 119 mmol) was added drop wise at 0° C. The reaction mixture was quenched with a saturated aqueous solution of NH4Cl (20 mL), then diluted with water (200 mL) and extracted with EtOAc (150 ml). The organic layer was dried (Na2SO4) and concentrated under reduced pressure to afford the title compound as a yellow oil (16.5 g, 98%). 1H NMR (CDCl3, 400 MHz) δ 7.55 (1H, s), 7.29 (1H, m), 6.86 (1H, d), 4.45 (2H, s), 3.55 (1H, m), 3.41 (1H, m), 2.82 (1H, m), 2.12-2.51 (1H, m), 1.91 (1H, m) 1.81 (1H, m), 1.58 (1H, m), 0.99 (3H, d).
