Procedure

A solution of {(S)-1-Aminomethyl-5-[4-((R)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-phenyl]-3,3-dimethyl-pentyl}-carbamic acid tert-butyl ester (0.13 g, 0.28 mmol) and TFA (1 ml) in DCM (5 ml) is stirred at room temperature for 1 hour, then loaded onto an SCX-2 cartridge which has been pre-eluted with MeOH. The cartridge is eluted with MeOH (2×5 ml), followed by 7M NH3 in MeOH (2×5 ml) to yield (S)-3-[4-((S)-5,6-Diamino-3,3-dimethyl-hexyl)-phenoxy]-propane-1,2-diol in 80% purity as a colourless oil; [M+H]+ 311
