実験手順
The title compound was prepared from Nα-isobutyl-Nα-(4-methylbenzenesulfonyl)-Nε-iodoacetyl-L-lysine (150 mg, 0.29 mmol, example 105, step B) by following the indications of general procedure H using DIEA (0.10 mL, 0.57 mmol) and 4-amiinopyridine (76 mg, 0.59 mmol). The crude material was purified by preparative HPLC. The product was isolated as a solid (39 mg, 28% yield).
