実験手順

A solution of (5R,9R)-tert-butyl 1-(9H-fluoren-9-yl)-9-(hexadecyloxy)-3-oxo-2,11-dioxa-7-thia-4-azaheptacosane-5-carboxylate in 40% TFA in DCM (0.3 M) was stirred at room temperature until complete deprotection of tert-butyl group (2 hours). The reaction mixture was diluted in MTBE, washed three times with 1 M citric acid (pH 3), and once with 1:2 HCl (3 M)/brine. The organic layer was dried over anhydrous Na2SO4 and concentrated en vaccuo. The resulting waxy solid was used in the next step without further purification.
