실험 절차

A solution of 6.0 grams (0.01 mole) (±)-1-S-hexadecyl-3-O-tritylthioglycerol in 250 milliliters of THF was added to a slurry of 0.4 grams (0.014 mole) 80% NaH (oil dispersion) in 50 milliliters of THF and the reaction mixture stirred at room temperature for one hour. Then 1.4 gram (0.13 mole) of CH3I was added and the reaction allowed to proceed at room temperature for 24 hours. The reaction mixture was then diluted with 300 milliliters of distilled water and extracted twice with 200 milliliter portions of ether. The nonaqueous extracts were combined, dried over anhydrous sodium sulfate, filtered and removed in vacuo to provide 6.0 grams of crude product as an oil. 1H-NMR (CDCl3): delta, 0.7-1.7[m, 31H, (CH2)14CH3 ], 2.3-2.8(m, 4H, CH2 --S--CH2), 3.25(m, 5H, CH3O, CH--CH2 --O), 3.6-4.0(m, 1H, CH), 7.6-7.0[m, 15H, C(C6H5)3 ].
