Versuchsvorschrift

A solution of methyl 6-((1R,2S)-2-(tert-butoxycarbonylamino)cyclohexylamino)-4-cyano-2-(1-methyl-1H-pyrazol-4-yl)nicotinate (110 mg, 0.242 mmol) and palladium on carbon (2.58 mg, 0.024 mmol) in MeOH (5 mL) and HOAc (1 mL) was stirred at RT overnight under H2 atmosphere. After reaction, the mixture was filtered through Celite, the filtrate was evaporated, and the residue was diluted with MeOH and sat aq NaHCO3. The mixture was stirred at RT for 30 min and extracted with EtOAc. The organic phase was washed with brine, dried over MgSO4, and evaporated. The residue was purified by chromatography on SiO2 and preparative HPLC to give the title compound (60 mg, 58.1%). 1H NMR (500 MHz, CDCl3) δ ppm 1.26-1.87 (m, 17 H), 3.91 (s, 3 H), 4.25 (br s, 2 H), 5.16-5.49 (m 2 H), 6.23 (br s, 1 H), 6.75 (br s, 1 H), 8.18-8.44 (m, 1 H), 8.76-9.05 (m, 1 H).
