Versuchsvorschrift

To 200 mg (0.512 mmol) tert-butyl 3-amino-5-(3,5-dicyano-2,6-dimethyl-1,4-dihydropyridin-4-yl)-1H-indazole-1-carboxylate (Example 3A) in dichloromethane (4 ml) were added 309 mg (1.54 mmol) ethyl 3-(chlorosulfonyl)propanoate and 0.21 ml (1.54 mmol) triethylamine. The mixture was stirred at room temperature for 12 h and then concentrated under reduced pressure. The residue was dissolved in ethyl acetate, and the solution was washed with saturated aqueous sodium hydrogencarbonate solution, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The crude product was purified by preparative RP-HPLC (acetonitrile/water gradient) to yield 41 mg (14% of th.) of the title compound.
