Reaction Steps
Racemic α-(aminomethyl)benzenemethanol (13.7 g) and bis(1,1-dimethylethyl)carbonate (21.8 g) were dissolved in methanol (200 ml) and 10% aqueous sodium carbonate (200 ml) added. The mixture was stirred at room temperature for 24 h, poured into 2M hydrochloric acid and extracted with ethyl acetate. Evaporation of the extract and trituration with ethyl acetate/hexane gave the sub-title compound as a pale yellow solid (27.6 g).
