Vorschrift

Detritylation of 3-dodecyloxy-2-decyloxy-1 -triphenylmethoxypropane was accomplished using p-toluenesulfonic acid (0.9 g) in CHCl3 :MeOH (72 mL:36 mL) (stirred at room temperature for 48 h, added 10% sodium bicarbonate, extracted with CHCl3, dried over magnesium sulfate, and concentrated). The residue was purified by column chromatography using a gradient of hexanes:ethyl acetate (20:1 to 5:1) to give 3.5 g (63%) of pure 3-dodecyloxy-2-decyloxy-1-propanol.
