Procedure

Using the procedure described in example 3, a solution of 1-(2-adamantan-1-yl-2-oxoethyl) L-proline (104.6 mg, 0.36 mmol, 1.0 eq), triethylamine (150 uL, 1.07 mmol, 3.0 eq), and THF (1.5 mL), was treated with isobutyl chloroformate (51 uL, 0.39 mL, 1.1 eq), then with glycine N-benzylamide (88.2 mg, 537 umol, 1.5 eq). Workup as before provided 53.9 mg (34%) of glycine, N-[1-(2-adamantan-1-yl-2-oxoethyl)-L-prolyl] benzylamide. as a white foam.
