Procedure

To a solution of 3-(benzyloxycarbonylamino)-4-cyclobutyl-2-hydroxybutanoic acid (600 mg, 1.95 mmol) in DCM (20 mL) was added HOSu (337 mg, 2.93 mmol), EDC (562 mg, 2.93 mmol). After stirring for 1 hour, cyclopropylamine (223 mg, 3.9 mmol) was added to the above mixture. The product was extracted with EtOAc. The combined organic layer was then washed with HCl (1N), water, NaHCO3, and brine and then concentrated in vacuo to afford benzyl 1-cyclobutyl-4-(cyclopropylamino)-3-hydroxy-4-oxobutan-2-ylcarbamate (530 mg). (M+1) 347.
