To a solution of 4-(4-isopropoxymethylbenzyl)phenyl carbamic acid 2-trimethylsilanylethyl ester (734 mg, 1.84 mmol) in dry dimethyl sulfoxide at 20° C. under argon atmosphere was added tetra-n-butylammonium fluoride in tetrahydrofuran (5.52 mL, 5.52 mmol). After the mixture was stirred for 1 hour, the solution was partitioned between water (50 mL) and diethyl ether (50 mL). The aqueous phase was extracted with diethyl ether (2×20 mL), and the combined organic layers were washed with water and brine, dried (Mg2SO4), and evaporated in vacuo. The crude product was purified by flash chromatography to give pure 4-(4-isopropoxymethyl-benzyl)-phenylamine (405 mg, 86%) as a clear oil.
