Versuchsvorschrift

To a stirred solution of potassium 1-({(3S)-3-[(2-oxo-2-{[(2R)-2′-oxo-1,1′,2′,3-tetrahydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-5-yl]amino}ethyl)amino]-3-phenylpropyl}amino)cyclopentanecarboxylate from Step B (0.147 g, 0.249 mmol) in DMF (8.3 mL) was added EDCI (0.0720 g, 0.374 mmol) and HOAt (0.0340 g, 0.249 mmol). The reaction mixture was then heated to 40° C. After 1 h, additional EDCI (0.0350 mg) was added and the reaction temperature was increased to 50° C., for 15 h. The reaction was allowed to cool to ambient temperature before being diluted with 5% aqueous sodium bicarbonate (100 mL) and chloroform (100 mL). The organics were washed successively with water (100 mL) and saturated brine (100 mL). The combined organics were dried over sodium sulfate, filtered and concentrated in vacuo to give an oil. This oil was purified by silica gel chromatography, eluting with a gradient of CH2Cl2:MeOH-99:1 to 91:9, to give the title compound. MS: m/z=536 (M+1). HRMS: m/z=536.2694; calculated m/z=536.2656 for C32H34N5O3.
