Procedure

To a solution of 5-[4-cyano-2-(formylaminomethyl)phenoxy]-1,3-dihydro-1-hydroxy-2,1-benzoxaborole (250 mg, 0.812 mmol) in ethanol (16 mL) was added 6 M HCl (4 mL), and the mixture was refluxed for 2 h. The solvent was removed under reduced pressure, and the residue was treated with ether to give 5-(2-aminomethyl-4-cyanophenoxy)-1,3-dihydro-1-hydroxy-2,1-benzoxaborole hydrochloride (247 mg, 98%).
