The hot reaction mixture was filtered and the filtrate was evaporated. The residue was portioned between EtOAc and water; the organic phase was washed with brine and dried over Na2SO4. The solvent was removed affording N-(4-amino-2-(cyclopropylmethoxy)phenyl)-methanesulfonamide (0.679 g, 2.65 mmol, 91% yield, MS/ESI+ 256.9 [MH]+).
