실험 절차

A solution of 4-((alpha-S)-alpha-((2S,5R)-2,5-dimethyl-1-piperazinyl)benzyl)-N,N-diethylbenzamide (9.128 g, 24.05 mmol) in acetonitrile (150 mL) was added to sodium iodide (360 mg, 2.4 mmol) and stirred under nitrogen during the addition of triethylamine (12 mL, 8.76 g, 86.6 mmol), followed by 3-fluorobenzyl bromide (5.9 mL, 9.09 g, 48.1 mmol). An immediate turbidity was observed on addition of the fluorobenzyl bromide, thickening to a white crystalline precipitate over one hour. The reaction mixture was stirred under nitrogen overnight at room temperature. The solvent was removed by evaporation, and saturated sodium bicarbonate solution (25 mL) was added to the residue. The copious white precipitate was collected by filtration, washed well with water and dried under vacuum at room temperature. (10.54 g, 89.2%). Calc. for C31H38FN3O 0.2 H2O: C, 75.79; H, 7.88; N, 8.55; F, 3.87. Found C, 75.80; H, 7.78; N, 8.49; F, 3.75%.
