Reaction Steps

The mixture of 2.0 gr DL-N benzensulfonyl-3 aminobutyric acid (I), 1.0 gr 2-butanol, 30 ml toluene and 0.04 gr H2SO4 (conc) was heated under reflux for ca 6 hr. The water formed in the reaction was separated by azeotropic distillation. The cooled reaction mixture was washed twice with bicarbonate 2%, and dried over magnesium sulfate. Distillation of the solvent and alcohol yield 1.8 gr procuct, confirmed by spectroscopy.
