Reaction Conditions

Reaction Steps

To N-(t-Butyloxycarbonyl)-2-(2-methoxyphenyl)-ethylamine (182.7 mmol, 45.9 g) in dry tetrahydrofuran (200 mL) at 0° C. was added, in portions, lithium aluminum hydride (219.2 mmol, 8.3 g) under N2. After stirring at 0° C. for 1 hour, the ice-bath was removed and then the reaction heated to reflux for 24 hours, cooled to room temperature then to 0° C.; the excess lithium aluminum hydride was destroyed very carefully with 20% potassium hydroxide solution (1.3 equivalent). After removing the salt by filtration, the filtrate was dried then evaporated to dryness to give product as a white solid (26.2 g, 87%).
