실험 절차

A solution of 5-[(2R)-2-({(2R)-2-{[tert-butyl(dimethyl)silyl]oxy}-2-[4-hydroxy-3-(hydroxymethyl)phenyl]ethyl}amino)propyl]-1H-indole-2-carboxylic acid (Preparation 5, 0.25 g, 0.50 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (106 mg, 0.55 mmol), hydroxybenzotriazole (75 mg, 0.55 mmol) in N,N-dimethylformamide (5 ml) was treated with triethylamine (0.15 ml, 0.55 mmol) and 2-methoxybenzylamine (0.07 ml, 0.55 mmol) and the resulting suspension left to stir at room temperature under a nitrogen atmosphere for 18 hours. The solvent was removed in vacuo and the residue partitioned between dichloromethane (50 ml) and saturated aqueous sodium bicarbonate (20 ml). The organic phase was separated, dried (sodium sulphate) and the solvent removed in vacuo. The residue was purified by flash column chromatography on silica gel eluting with dichloromethane:methanol (95:5 changing to 90:10, by volume) to give the title compound as a colourless foam (76 mg).
