Reaction Steps

Hydrazine (2.2 ml of a 1M solution in THF, 2.2 mmol) is added to a solution of [(S)-5-[4-((R)-2,2-Dimethyl-[1,3]dioxolan-4-ylmethoxy)-phenyl]-1-(1,3-dioxo-1,3-dihydro-isoindol-2-ylmethyl)-3,3-dimethyl-pentyl]-carbamic acid tert-butyl ester (0.16 g, 0.28 mmol) in ethanol (5 ml), and the resulting colourless solution is heated at 45° C. overnight. The reaction is allowed to cool to room temperature, and diethyl ether (30 ml) is added and the resulting white suspension cooled at 0° C. for 30 minutes. The white solid is removed by filtration, and the solvent removed in vacuo to yield {(S)-1-Aminomethyl-5-[4-((R)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-phenyl]-3,3-dimethyl-pentyl}-carbamic acid tert-butyl ester as a colourless oil; [M+H]+ 451.
