Reaction Steps
In a three neck-flask, 150 mg of 20% palladium/carbon were added to the solution of (2R)-5-(Benzyloxycarbonylamino)-2-[(R)-3-benzyloxytetradecanoylamino]pentan-1-ol (3.0 g, i.e. 5.27 mmol) and 6 ml of triethylamine in 300 ml of HPLC-grade ethanol, Air was discharged under vacuum then the flask was loaded with hydrogen. The reaction mixture was stirred at room temperature for 2 hours then the catalyst was filtered off by membrane filtration and the filtrate was concentrated to provide a homogenous white solid as shown by TLC, to be used as such in the next step with no further purifcation, Rf=0.2, dichlormethane-methanol-triethylamine 5:10.5, m.p.=47–48° C.
