실험 절차
To (2R,5S)-4-carboxymethyl-2-methyl-5-((R)-3-methyl-morpholin-4-ylmethyl)-piperazine-1-carboxylic acid tert-butyl ester (1.5 g, 4.04 mmol) and 6-(2-fluoro-benzyl)-3,3-dimethyl-2,3-dihydro-1H-pyrrolo[3,2-b]pyridine (1.14 g, 4.45 mmol) in DMF (20.2 mL) were added 0-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (2.31 g, 6.1 mmol) and N,N-diisopropylethylamine (1.41 mL, 8.1 mmol) at room temperature. The reaction was stirred at room temperature for 18 h. Saturated aqueous sodium hydrogen carbonate was added and the mixture extracted with diethyl ether (3×). The combined organic extracts were washed with water (3×) and brine (3×) then dried with sodium sulfate, filtered and concentrated. Chromatography (silica gel, gradient elution, 0-100%, EtOAc in petrol 40-60) gave the title compound (1.43 g), MS: [M+H]+=610.
