Yield: 99%
Reaction Conditions:
with sodium hydroxide in 1,4-dioxane;water at 20; for 18 h;
Steps:
1.A
A solution of 4-iodo-benzylamine (18.64g, 80mmol), dι'-tert-buty dicarbonate (19.21g, 88mmol), and NaOH (4.8Og, 120mmol) in dioxane/H2O (1 :1 , 25OmL) was stirred at room temp for 18 hours. The solvent was removed and the residue was dissolved in EtOAc (20OmL). The organic layer was washed with H2O (5OmL), HCl (IN, 2x 5OmL), NaHCO3 (10%, 5OmL) and H2O (5OmL). The organic solution was dried over anhydrous Na2SO4. The solvent was evaporated to give (4- iodobenzyl)carbamic acid tert-butyl ester (1, 26.5Og, 99%).
