Yield: 55%

Reaction Conditions:

with potassium hydroxide in ethanol at 80; for 3 h;

Steps:

1.2; 2.2 Step 3
Take all the above crude secondary amine derivatives B and add KOH 10mmol (0.561g)Add to a round bottom flask, then add 100 mL of ethanol, and stir to dissolve at 80°C;Subsequently, the ethanol was distilled off under reduced pressure. Increase the temperature to 80°C again, slowly add 120mmol (32.400g) of methyl palmitate dropwise under reduced pressure, and the drop will be completed in about 3 hours;The reaction was continued for 6 hours, and the reaction was stopped. Recrystallization of n-hexane/ethanol to obtain Ceramide E,The total yield is 55%, and the purity is 98%.
