PROCEDURE

实验过程

According to the procedure of Preparation 19 d), tert-butyl (3R)-3-({[(1S)-2,2-dimethyl-1-(carboxy)propyl]amino}carbonyl)-6-(3′-methoxy-2-methylbiphen-4-yl)hexanoate (660 mg, 1.26 mmol) was reacted with (1S)-2-methoxy-1-phenylethylamine (190 mg, 1.260 mmol). Work-up as above, followed by flash chromatography (eluting with hexane:ethyl acetate=3:1) to give tert-butyl (3R)-3-({[(1S)-2,2-dimethyl-1-({[(1s)-2-methoxy-1-phenylethyl]amino}carbonyl)propyl]amino}carbonyl)-6-(3′-methoxy-2-methylbiphen-4-yl)hexanoate (672 mg, 81%) as a colourless foam.
