Reaction Steps
To a solution of 1.0 g of 2-amino-5-chloro-α-(2-chlorophenyl)benzyl alcohol in 12 ml of dichloromethane, a solution of 0.8 g of anhydrous trifluoroacetic acid in 2 ml of dichloromethane was added. After reaction, an aqueous solution of sodium hydrogen carbonate was added, and the organic layer was dried, after which the solvent was removed and the residue was recrystallized from hexane to yield 1.3 g of a crystal.
