実験手順

A mixture of 5-[(R)-2-{(R)-2-[3-(2-aminoethyl)phenyl]-1-methylethylamino}-1-(tert-butyldimethylsilanyloxy)ethyl]-8-benzyloxy-1H-quinolin-2-one (0.586 g, 1.00 mmol); [4-({3-[4-(biphenyl-2-ylcarbamoyloxy)piperidin-1-yl]propionyl}methylamino)-phenyl]acetic acid (0.516 g, 1.00 mmol); 2-chloropyridium triflate on Wang resin (polymer-supported Mukaiyama reagent) (1.19 mmol/g loading; 1.68 g, 2.00 mmol); and N,N-diisopropylethylamine (522 μL, 3.00 mmol) in DCM (5.00 mL) was stirred at room temperature overnight. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (0-5% MeOH in DCM) to give the title compound (412 mg, 38% yield) as an off-white oil.
