Reaction Steps

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.
