Reaction Steps

Next, NaBH4 (3.8 g, 100 mmol) and LiBr (8.7 g, 100 mmol) were added to THF (100 ml), and the mixture was stirred at 80° C. for 1 hour. To this mixture, [(3-methoxyphenyl)methylamino]acetic acid ethyl ester (7.4 g, 33.1 mmol) dissolved in THF (20 ml) was added dropwise at room temperature. The mixture was stirred at 80° C. for 5 hours and further at room temperature for 16 hours. After the reaction solvent was evaporated to about half, KH2PO4 (1 M, 200 ml) was slowly added dropwise thereto. The organic layer was extracted with dichloromethane (50 ml) times and dried over Na2SO4 to give crude 2-[(3-methoxyphenyl)methylamino]ethanol (yield: 8.1 g).
