Reaction Steps
Sodium hydride (0.076 g, 1.89 mmol) is added to a 0° C. solution of racemic (3aRS,5RS,6aSR)-6a-(3-bromophenyl)-1-(2,4-dimethoxybenzyl)hexahydro-1H-cyclopenta[c]isoxazol-5-ol (0.684 g, 1.57 mmol) in DMF (7 mL). The reaction is warmed to room temperature for 10 minutes and then cooled to 0° C. Methyl iodide (0.246 g, 1.73 mmol) is added and the reaction is stirred at room temperature for 6 hours. Additional sodium hydride (0.032 g, 0.790 mmol) and methyl iodide (0.112 g, 0.790 mmol) is added and the reaction is stirred at room temperature for 18 hours. The reaction is quenched with water and extracted with ethyl acetate. The organic layer is dried over sodium sulfate, filtered and the solvent is removed under reduced pressure. The resulting residue is purified by silica gel chromatography with 10% ethyl acetate in CH2Cl2 to give the title compound (0.443 g, 63%). ES/MS m/e (79Br/81Br) 448, 450 (M+1).
