Flow chemistry is a rapidly emerging technology within the pharmaceutical industry, both within medicinal and development chemistry groups. The advantages of flow chemistry, increased safety, improved reproducibility, enhanced scalability, are readily apparent, and we aimed to exploit this technology in order to provide small amounts of pharmaceutically interesting fragments via a safe and scalable

The preparation of different aminoindazoles by nucleophilic aromatic photosubstitution of nitroindazoles by amines is described. In this manner, the amino, methylamino, dimethylamino and dimethylamino substituents are introduced in 3,4,5 or 7-position. The irradiation in the presence of ethanol gives ethoxyindazoles in only four cases. Two demethylation reactions have been observed: the first one concerns
