Reaction Steps

14.3 g (60.2 mmol) Diethyl phenylmalonate, 9.1 g (60.2 mol) 5-fluoro-1H-indazol-3-ylamine and 25.3 mL tributyl amine were heated for 15 h at 180° C. The reaction mixture was treated with 2M sodium hydroxide and water and extracted with tert-butyl methyl ether. The organic phase was discarded and the aqueous phase was acidified with conc. hydrochloric acid. The precipitate was collected by filtration and washed with water to obtain 14 g of the desired product which is 90% pure. MS (Cl, M+1): 296
