Versuchsvorschrift
To an ice-cold solution of N-(5-bromo-2-fluoropyridin-3-ylcarbamothioyl)benzamide II (1.80 g, 5.08 mmol) in THF (20.0 mL) was added a solution of NaOH (1.0 g, 22.0 mmol, dissolved in 10.0 mL H2O). The reaction mixture was then heated to 60° C. for 16 h. After the completion of the reaction (TLC monitoring), the reaction mixture was concentrated, added water and extracted with EtOAc (3×150 mL). The combined organics was washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure to obtain the desired product (1.60 g, 95%). 1H NMR (400 MHz, DMSO-d6): δ 7.42 (m, 3H), 7.82 (d, J=2.0 Hz, 1H), 8.14 (m, 2H) and 8.18 (d, J=2.0 Hz, 1H).
