4-Anisaldehyde (18.1 g, 133 mmol) was added to a solution of D-alaninol (10 g, 133 mmol) in methanol (100 ml) with vigorous stirring and the mixture was stirred for 30 minutes. Sodium borohydride (5.0 g, 132 mmol) was added to the ice-cooled solution and stirred for one hour at room temperature. When the reaction was complete (checked by thin layer chromatography), excess reagent was decomposed by the addition of water. The solution was partitioned between water and chloroform. The organic layer was washed with brine, dried over magnesium sulfate. Removal of the solvent under reduced pressure afforded (2R)-2-(4-Methoxybenzylamino)-propan-1-ol (26 g, 133 mmol, 100%) as white crystals.
