Participants

Reaction Steps

A solution of 2-nitrobenzenesulfonylchloride (11 g; 50 mmol) and NaOH (2.1 g; 53 mmol) in H2O (100 ml) was added DL-leucine (6.55 g; 50 mmol) and left over night with stirring at rt. The reaction mixture was added 4 M NaOH (12.5 ml) and filtered. The filtrate was acidified with 1 M HCl (50 ml) and extracted with EtOAc. The combined organic fractions were dried (Na2SO4) and evaporated to dryness to give 6.7 g (42%) product.
