Reaction Steps

A solution of N-tert-butoxycarbonyl-O-benzyl-D-valinol (9.95 g, 34 mmol) in formic acid (50 ml) was stirred for 4 hours at room temperature. After removal of the formic acid in vacuo, the sticky residue was dissolved in water (100 ml), neutralized with a saturated solution of sodium bicarbonate (100 ml) and the organic material extracted twice with ethyl acetate (2×200 ml). The organic phases were washed until neutral with water (2×200 ml) and the combined organic layers were dried on sodium sulfate. Filtration and evaporation of the solvent in vacuo afforded the title amine as a slightly yellowish oil (5.20 g, 79%).
