실험 절차

0.2 g of 5% strength palladium on charcoal is added to a solution of 2.8 g of the laevorotatory isomer of tetra-n-butylammonium 1-(3-nitrophenyl)ethanesulphonate in 50 cm3 of ethanol. The suspension is stirred for 2 hours at a temperature of about 25° C. under a hydrogen atmosphere (100 kPa). The catalyst is filtered off and the filtrate is concentrated to dryness under reduced pressure (2.7 kPa) at 40° C. 2.8 g of the laevorotatory isomer of tetra-n-butylammonium 1-(3-aminophenyl)ethanesulphonate are thus obtained in the form of an oil, used as such in the subsequent syntheses.
