Procedure

A mixture of 4.6 g of 1-fluoro-2-methyl-4-nitrobenzene and 3 ml of hydrazine hydrate in 45 ml of 2-propanol is heated to reflux for 2 hours. 3 ml of hydrazine hydrate are added, refluxing is continued for 2 hours and the mixture is left overnight with stirring at RT. The precipitate formed is drained. 3.53 g of the expected product are obtained, m.p.=182° C.
