Versuchsvorschrift

HATU (464 mg, 1.22 mmol, 1.0 equiv.) and DIPEA (0.8 ml, 4.88 mmol, 4.0 equiv.) were added at 0° C. to a suspension of 2-(7-((tert-butoxycarbonylamino)methyl)-1H-indol-1-yl)acetic acid (372 mg, 1.22 mmol, 1.0 equiv.) in THF (8 ml), and the mixture was stirred for 15 min. A solution of 3-pyridin-4-yl-3,9-diazaspiro[5.5]undecane (F-14) (283 mg, 1.22 mmol, 1.0 equiv.), dissolved in a mixture of THF (4 ml) and DMF (0.5 ml), was added, and stirring was carried out for 14 h at RT. The reaction mixture was diluted with ethyl acetate (30 ml) and extracted with sodium bicarbonate solution (2×20 ml), NH4Cl solution (2×20 ml), water (20 ml) and sat. NaCl solution (20 ml) and dried over Na2SO4. The solvent was removed under vacuum and the crude product was purified by column chromatography (Alox neutral; 0.5% MeOH/DCM), and the desired product was thus obtained in the form of a white solid.
