To a solution Ethyl 2-methyl-5-(4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)benzamido)benzoate (300 mg, 0.65 mmol) in dried THF (2.2 mL) was added Lithium aluminium hydride 2.0M THF solution (0.48 mL, 0.98 mmol) at 0° C. The reaction mixture was stirred for 2 hours at room temperature. When the reaction was completed, the reaction mixture was diluted with ethyl ether (2.0 mL) and added water very slowly to decompose the excess of the reagent. To a reaction mixture was added MgSO4, celite filtered and concentrated under reduced pressure. The title compound (230 mg, 84% yield) was used next step without further purification. MS m/z: 422 [M+1].
