Reaktionsschritte

To 0.11 g of methyl N-[(4′-amino-1,1′-biphenyl-4-yl)sulfonyl]-N-methyl-D-valinate in 4 mL dichloromethane cooled in ice bath, was added 0.058 g of 2-benzofurancarbonyl chloride, and N,N-diisopropylethylamine (0.15 mL) was dropped in. The reaction was stirred at room temperature overnightand then diluted with dichloromethane. The organic layer was washed with water, 5% HCl, and brine, dried over sodium sulfate, filtered, concentrated, and purified by column chromatography eluting with hexane:ethyl acetate (2:1) to provide 0.13 g of methyl N-({4′-[(1-benzofuran-2-ylcarbonyl)amino]-1,1′-biphenyl-4-yl}sulfonyl)-N-methyl-D-valinate. Yield 86.6%. m.p. 67-69° C. MS: 521.3 (M+H)+.
