実験手順
tert-butyl 1-((4-(4-(3-aminopropoxy)benzoyl)phenyl)amino)-3,6,9,12-tetraoxapentadecan-15-oate (3.24 g, 5.63 mmol) was dissolved in a solution of DCM:TFA (2:1, 20 ml) and stirred ca. 1 h. Upon completion, reaction was then concentrated under reduced pressure, co-evaporated with toluene, and dried on oil pump for 5 hs to yield 3.20 g of crude 1-((4-(4-(3-aminopropoxy)benzoyl)phenyl)amino)-3,6,9,12-tetraoxapentadecan-15-oic acid as yellow oil. The crude product was used without any further purification.
