实验步骤: Into a 100-mL 3-necked round-bottom flask, was placed a solution of 2-((2,4-dichlorobenzyl)(methyl)amino)-1-phenylethanol (3.4 g, 11.00 mmol, 1.00 equiv) in dichloromethane (15 mL). This was followed by the addition of sulfuric acid (15 mL) dropwise with stirring at 0° C. The resulting solution was stirred for 2 h at 0° C. in a water/ice bath. The pH value of the solution was adjusted to 7 with 1M sodium hydroxide. The resulting solution was extracted with ethyl acetate (3×60 mL) and the combined organic layers dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with petroleum ether:ethyl acetate (80:1). This resulted in 1.6 g (50%) of the title compound as a colorless oil. Into a 100-mL 3-necked round-bottom flask, was placed The resulting solution was stirred for 2 h at 0° C. in a water/ice bath The resulting solution was extracted with ethyl acetate (3×60 mL) the combined organic layers dried over anhydrous sodium sulfate concentrated under vacuum

实验步骤: Into a 250 ml 3-necked roundbottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-((2,4-dichlorobenzyl)(methyl)amino)-1-phenylethanone (4.3 g, 14.01 mmol, 1.00 equiv) in methanol (50 mL). This was followed by the addition of NaBH4 (1.5 g, 39.47 mmol, 2.82 equiv) in several batches at 0° C. The resulting solution was stirred for 30 min at 0° C. in a water/ice bath. The reaction was then quenched by the addition of 20 mL of acetone. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:80˜1:20). This resulted in 3.4 g (79%) of the title compound as a white solid. Into a 250 ml 3-necked roundbottom flask purged maintained with an inert atmosphere of nitrogen The reaction was then quenched by the addition of 20 mL of acetone The resulting mixture was concentrated under vacuum
