Dichloromethane → {[(2S)-2-amino-4-methylpentyl]oxy}(tert-butyl)dimethylsilane

Participants

Reaction Steps

To a room temperature dichloromethane (100 mL) solution of L-leucinol (6.0 g) was added triethylamine (11 mL), DMAP (0.1 g) and t-butyldimethylsilyl chloride (8.5 g). The mixture was stirred at room temperature for 2 hours and then water was added. The organic layer was separated and the aqueous further extracted with dichloromethane. The combined organic layers were washed with brine, dried with magnesium sulfate and the solvent was removed in vacuo to yield the title compound, a residue which was used as such in the next reaction. 1H NMR (CD3COCD3) δ 3.48 (m, 2H), 3.32 (m, 1H), 2.76 (m, 1H), 1.78 (m, 1H), 1.22-1.02 (m, 2H), 0.88 (m, 15H), 0.06 (s, 6H).
