PROCEDURE

实验过程

Using the General Procedure for N-alkylation: A solution of (2S)-2-(tert-butoxycarbonylamino)-5-(5,6,7,8-tetrahydroquinolin-8-ylamino)-pentanoic acid tert-butyl ester (0.700 g, 1.67 mmol), 1-(tert-butoxycarbonyl)-2-(chloromethyl)-benzimidazole (0.690 g, 2.59 mmol) and N,N-diisopropylethylamine (0.60 mL, 3.44 mmol) in CH3CN (16 mL) was heated at 60° C. for 24 hours. Purification of the crude material by column chromatography on silica gel (50:1 CH2Cl2—MeOH) provided 0.830 g (77%) of 2-{[(4-tert-butoxycarbonyl-4-tert-butoxycarbonylamino-butyl)-(5,6,7,8-tetrahydroquinolin-8-yl)-amino]-methyl}-benzoimidazole-1-carboxylic acid tert-butyl ester as a tan foam.
