Triethylamine → L-Isoleucine

Participants

Reaction Steps

Using the procedure described in Example 5, a solution of L-proline-L-isoleucine benzylamide (160 mg, 0.50 mmol), and triethylamine (352 uL, 2.53 mmol, 5.0 eq), in THF (2 mL), was treated with 232 mg (1.0 mmol) of 1-chloro-2-(4-pentylcyclohexyl)-2-oxoethane (prepared from trans-4-pentylcyclohexanecarboxylic acid using the procedure described in example 1) to provide 154 mg, (25%) of L-isoleucine, N-[1-(2-(4-pentylycyclohexyl)-2-oxoethyl)-L-prolyl] benzylamide.
