Procedure

0.18 g (0.26 mmol) (3R)-tert-butyl 3-(3,5-difluorophenyl)-5-oxo-4-(2-oxo-2-(2′-oxo-1′,2′,5,7-tetrahydrospiro[cyclopenta[b]pyridin-6,3′-pyrrolo[2,3-b]pyridin]-3-ylamino)ethyl)-8,11-dioxa-1,4-diazaspiro[5.6]dodecane-1-carboxylate were combined with 30 ml of a 1N methanolic hydrochloric acid solution and stirred for 1 h at 50° C. The reaction mixture was concentrated by rotary evaporation and purified by HPLC. The product fractions were evaporated down, neutralised with sodium hydrogen carbonate and the aqueous phase was extracted with DCM. The organic phase was concentrated by rotary evaporation. The residue was triturated with diethyl ether, suction filtered, washed with diethyl ether and dried.
