Reaction Steps

5-(3,5-Difluoro-benzyloxy)-1H-indazol-3-ylamine (550 mg, 2 mmol) was dissolved in sym-collidine, cooled to 4° C. and treated with neat 3-chloromethyl-benzoyl chloride (0.34 mL, 2.4 mmol). After 1 hour the reaction mixture was added drop wise into iced water, with stirring and separation of a yellow oil occurred. Then, EtOAc (50 mL) and 2N HCl (25 mL) were added. The organic phase was separated, washed with aqueous NaHCO3 (50 mL), brine, dried over sodium sulfate and evaporated to dryness. After purification over silica gel (eluent: DCM:MeOH 95:5) 378 mg of title compound were obtained as a whitish solid in 56% yield.
