Steps:
4.1.1. General procedure for the synthesis of fluoro-1H-indazoles 2c, 2d
General procedure: The title compounds were obtained by modifying a method described by Lukin et al. [63]. To the properly substituted 2-fluorobenzaldehyde (5 g, 35 mmol) was added hydrazine hydrate (12.9 g, 258 mmol, 12.5 ml). After stirring for 12-48 h (TLC control) at reflux water (20 ml) was added and the resulting mixture was cooled to 5 °C. The precipitate was collected by vacuum filtration. The filtrate was extracted with dichloromethane and the residue after evaporation was combined with the precipitate.
