MeOH.HCl (1.25 M, 11 ml, 13.9 mmol, 10 eq) was added to a flask charged with tert-butyl 3-(diethylamino)benzylcarbamate (0.3875 g, 1.4 mmol, 1 eq) at 0° C. under Ar. After stirring for 1.5 h at 0° C. the ice-bath was removed. After stirring at room temperature for 6 h, the solvent was removed in vacuo. The residue was stirred with saturated aqueous NaHCO3 for 30 min and extracted with CH2Cl2 (×2). The combined organics were dried over Na2SO4. The inorganics were filtered off, and the solvent was removed in vacuo to yield 0.191 g (1.07 mmol, 77% yield) of the product.
