Procedure

To (R)-3-(3,4-bis(aminomethyl)benzamido)-2-hydroxy-3,4-dihydro-2H-benzo[e][1,2]oxaborinine-8-carboxylic acid from Example 14 (44.1 mg) in methanol (2 mL) was added TEA (0.042 mL), AcOH (0.050 mL), acetone (0.030 mL), and sodium triacetoxyborohydride (70 mg). The resulting reaction mixture was stirred at room temperature for overnight. After removal of the solvents, the product was then purified by reverse phase HPLC and dried using lyophilization. ESI-MS m/z 412 (MH)+.
