Versuchsvorschrift
To a solution of N-(2-aminopyridin-4-yl)-2,6-dichlorobenzamide (150 mg, 0.54 mmol), 2-chlorocyclopropanecarboxylic acid (66 mg, 0.54 mmol) and HATU (381 mg, 1.08 mmol) in dry DMF (4.5 mL) was added DIPEA (144 mg, 1.08 mmol). The mixture was stirred at 110° C. in a microwave reactor for 1 hour. The mixture was cooled to room temperature and diluted with EtOAc (30 mL). The organic solution was washed with water (10 mL) and brine (10 mL), dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by prep-HPLC (Gilson GX 281, Shim-pack PRC-ODS 250 mm×20 mm×2, gradient: CH3CN/10 mm/L NH4HCO3, 17 min) to give the desired compounds.
