Versuchsvorschrift

A solution of tert-butyl (3-fluoropyridin-4-yl)carbamate (25.0 g, 125 mmol) in MeCN (200 ml), was added O-(2,4-dinitrophenyl)hydroxylamine (26.64 g, 125 mmol) in MeCN (200 ml), drop wise over 30 min at RT, reaction mass was stirred at 40° C. for 12 hrs, reaction mass was concentrated at temperature below 40° C. under reduced pressure to afford Int-11 (50 g) which was used in the next step without further purification.
