ConditionsYieldWith N-ethyl-N,N-diisopropylamine In ethanol at 20℃;Experimental ProcedureTo a solution of 2-(1 9-tert-l3utoxycarbonylnonade- canoylamino)pentanedioic acid 1 -tert-butyl ester 5-(2,5-di- oxopyrrolidin-1-yl) ester (2.50 g) and acetylamino}ethoxy)ethoxy]acetic acid (alternative name: H-OEG-OEG-OH)(1 .47 g) in ethanol (40 mE) was added DIPEA (1.26 mE). The mixture was stirred at room temperature overnight and then concentrated in vacuo. To the residue was added aqueous 0.1 N HC1 (150 mE) and ethyl acetate (200 mE). The layers were separated and the aqueous layer was extracted with ethyl acetate (100 mE). The combined organic layers were washed with water and brine, dried (magnesium sulphate) and concentrated in vacuo to give an oil, which crystallised on standing. Yield 96% (3.1 g). ECMS: Theoretical mass: 874.2.Found: 874.49.96%With N-ethyl-N,N-diisopropylamine In ethanol at 20℃;Experimental Procedure16.1 Step 1: 19-{(S)-1-tert-Butoxycarbonyl-3--methoxy}-ethoxy)-ethylcarbamoyl]-propylcarbamoyl}-nonadecanoic acid tert-butyl esterStep 1: 19-{(S)-1-tert-Butoxycarbonyl-3--methoxy}-ethoxy)-ethylcarbamoyl]-propylcarbamoyl}-nonadecanoic acid tert-butyl ester (0556) (0557) To a solution of 2-(19-tert-Butoxycarbonylnonadecanoylamino)pentanedioic acid 1-tert-butyl ester 5-(2,5-dioxopyrrolidin-1-yl) ester (2.50 g, (prepared similarly as described in WO 2005/012347) and acetylamino}ethoxy)ethoxy]acetic acid (1.47 g, alternative name: ∈-amino-3,6-dioxaoctanoic acid dimer, IRIS Biotech GmbH, Cat. No. PEG1221) in ethanol (40 ml) was added DIPEA (1.26 ml). The mixture was stirred at room temperature over night and then concentrated in vacuo. To the residue was added aqueous 0.1 N HCl (150 ml) and ethyl acetate (200 ml). The layers were separated and the aqueous layer was extracted with ethyl acetate (100 ml). The combined organic layers were washed with water and brine, dried (magnesium sulphate) and concentrated in vacuo to give an oil, which crystallized on standing. Yield 96% (3.1 g).
