Reaction Steps

2-Propanone (0.22 g, 3.7 mmol) was added to a solution of (S)-3-amino-2-hydroxypropanoic acid 2-propenyl ester hydrochloride (0.45 g, 2.5 mmol) and triethylamine (0.25 g, 2.5 mmol) in ethanol (2.5 ml). After 2 h the solution was cooled to 0° and sodium borohydride (0.15 g, 3.9 mmol) was added. After 20 min, water (0.4 ml) and dichloromethane were added. The mixture was filtered and the filtrate evaporated. The residue was dissolved in ether/water, the organic layer dried (MgSO4) and the solvent evaporated to give the sub-title ester (0.15 g).
