To a solution of 4-aminobenzyl alcohol (2.00 g, 16.2 mmol) in 10 mL of dioxane was added a solution of sodium hydroxide (0.65 g, 16 mmol) in 40 mL of water at room temperature. After addition of di-tert-butyl carbonate (4.95 g, 22.7 mmol), the reaction mixture was stirred at room temperature overnight. The mixture was diluted with diethyl ether, and the solution was washed with 1N HCl, saturated NaHCO3 aqueous solution, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo to obtain crude 4-(tert-butoxycarbonylamino)benzyl alcohol.
