Participants

Reaction Steps

A solution of (R)-N-[2-benzyloxy-5-(2-iodo-1-triethylsilyloxy-ethyl)phenyl]methanesulfonamide (2.09 g, 3.72 mmol), methyl (R)-3-(2-aminopropyl)-1H-indole-7-carboxylate (1.00 g, 3.72 mmol), diisopropyl-ethylamine (1.9 ml, 11.2 mmol) in tetrahydrofuran (30 ml)-acetonitrile (20 ml) is stirred at 110° C. for 18 hours in a sealed vessel. After cooling, to the reaction solution are added a saturated aqueous sodium hydrogen carbonate solution and a saturated brine, and the mixture is extracted with ethyl acetate. The organic layer is dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue is purified by silica gel column chromatography (chloroform/methanol=100/1→100/4) to give the title compound (1.05 g, yield: 42%).
