Reaction Steps

4-[(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]-N-[2-ethyl-4-(1,1,1,2,3,3,3-heptafluoro propan-2-yl)-6-methylphenyl]benzamide (0.80 g) was dissolved in ethanol (20 ml). To the solution, hydrazine monohydrate (0.28 g) was added and the mixture was stirred under heating at 60° C. for 4 hours. After adjusting to room temperature, the reaction solution was diluted with water and extracted twice with ethyl acetate. The organic phases were combined, washed with a saturated sodium bicarbonate solution and dried over magnesium sulfate. After filtering off the drying agent, the solvent was distilled off under reduced pressure to obtain 4-(aminomethyl)-N-[2-ethyl-4-(1,1,1,2,3,3,3-heptafluoropropan-2-yl)-6-methylphenyl] benzamide as a crude product (0.63 g). Without further purification, the crude product was used for the next reaction.
