Triethylamine → L-Isoleucine

Participants

Reaction Steps

Using the procedure described in Example 5 and Example 17, L-homoproline-L-isoleucine benzylamide (43 mg, 0.13 mmol), was treated with triethylamine (91 uL, 0.65 mmol, 1.5 eq), and benzyl 2-bromoacetate (41 uL, 0.26 mmol, 2.0 eq) in THF (2.5 mL). Purification by HPLC provided 54.3 mg of L-isoleucine, N-[1-(2-(carbobenzyloxymethylene)-2-oxoethyl)-L-homoprolyl] benzylamide.
