실험 절차

3'-(2-Aminoacetyl)-4'-fluoromethanesulfonanilide hydrochloride (21 g) was suspended in 210 ml of methanol, then a catalyst prepared from 50 mg of (2R,4R)-N-methylcarbamoyl-4-dicyclohexylphosphino-2-diphenylphosphinomethylpyrrolidine and 18 mg of di-μ-chlorobis(cyclooctadiene)dirhodium (I) was added thereto together with 19 mg of triethylamine and the mixture was reduced at 50° C. in an atmosphere of hydrogen of 20 atm. The reaction mixture was concentrated and made into a free base using ion exchange resin (Dowex 50W X2) to give 15.8 g of crude (R)-(-)-3'-(2-amino-1-hydroxyethyl)-4'-fluoromethanesulfonanilide.
