Triethylamine → L-leucine, N-[1-(2-adamantan-1-yl-2-oxoethyl)-L-prolyl] benzylamide

Participants

Reaction Steps

Using the procedure described previously, a solution of 1-(2-adamantan-1-yl-2-oxoethyl) L-proline (108 mg, 0.37 mmol, 1.0 eq), triethylamine (156 uL, 1.11 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-leucine N-benzylamide (123 mg, 570 umol, 1.5 eq). Workup as before provided 124 mg (68%) of L-leucine, N-[1-(2-adamantan-1-yl-2-oxoethyl)-L-prolyl] benzylamide.
