Reaction Steps

Using the procedure described in Example 3, a solution of 1-(2-adamantan-1-yl-2-oxoethyl) L-proline (109.1 mg, 0.37 mmol, 1.0 eq), triethylamine (156 uL, 1.12 mmol, 3.0 eq), and THF (1.5 mL), was treated with isobutyl chloroformate (53 uL, 0.41 mL, 1.1 eq), then with L-valine benzylamide (117.5 mg, 570 umol, 1.5 eq). Workup as before provided 127 mg (71%) of L-valine, N-[1-(2-adamantan-1-yl-2-oxoethyl)-L-prolyl] benzylamide as a white foam.
