Procedure

0.114 g (0.25 mmol) tert-butyl (R)-4-carboxymethyl-3-(3,5-difluoro-phenyl)-5-oxo-8,11-dioxa-1,4-diaza-spiro[5.6]dodecane-1-carboxylate were stirred overnight at RT with 67.9 mg (0.27 mmol) (S)-5-amino-1,3-dihydrospiro[inden-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one, 63.3 mg (0.33 mmol) 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, 44.6 mg (0.33 mmol) HOBT, 35 μl (0.25 mmol) TEA and 1.5 ml DMF. The solvent was spun off and the residue was stirred with 15 ml of a methanolic hydrochloric acid (1.25N) 1 h at 50° C. The reaction mixture was concentrated by rotary evaporation and the residue was purified by PR-HPLC. The product-containing fractions were concentrated by rotary evaporation and the residue was triturated with diisopropylether. After suction filtering the solid was washed with diisopropylether and dried.
