Procedure

To (R)-3-(2-(trans-4-aminocyclohexyl)acetamido)-2-hydroxy-3,4-dihydro-2H-benzo[e][1,2]oxaborinine-8-carboxylic acid (Example 6) in MeOH was added DIEA (2.5 eq), followed by isopropyl formimidate hydrochloride (1.2 eq). The reaction mixture was stirred at RT overnight. The mixture was then concentrated in vacuo and the crude product was purified using reverse phase HPLC to afford the title compound. ESI-MS m/z 374 (MH)+.
