Reaction Steps

To a stirred solution of benzyl trans-4-aminocyclohexylcarbamate (396 mg, 1.595 mmol) in CH2Cl2 (9 ml) was added dihydrofuran-3(2H)-one (151 mg, 1.754 mmol) followed by acetic acid (150 μL, 2.62 mmol) and sodium triacetoxyborohydride (439 mg, 2.073 mmol) under Argon. Stirred at 25° C. for 16 h, then concentrated in vacuo. The resulting residue was partitioned between EtOAc and 1M NaOH. The organics were combined, then washed with 1M NaOH (×2), water (×2), saturated brine (×2), then dried (Na2SO4), filtered and evaporated under reduced pressure to give racemic benzyl trans-4-(tetrahydrofuran-3-yl-amino)cyclohexylcarbamate (495 mg). The resulting residue was used in next step without further purification.
