Versuchsvorschrift
Using the procedure described in Example 5, treatment of a solution of L-proline-L-isoleucine benzylamide (58 mg, 0.18 mmol), with triethylamine (130 uL, 0.93 mmol, 5.0 eq), and N-chloroacetyl-2,4-dichloroaniline (53 mg, 0.22 mmol, 1.2 eq) in THF (7 mL), provided a crude product. A portion of the product was purified by preparative TLC to provide 30 mg (32%) of L-isoleucine, N-[1-(2,4-dichlorophenylcarbamoylmethyl)-L-proline] benzylamide.
