Procedure

1,3-Diacetoxy-2-octadecyl-2-(N-pentanoylamino)propane (400 mg) was dissolved in 8 ml of methanol and 17 mg of a 28% sodium methoxide-methanol solution was added thereto. The mixture was stirred at room temperature for 1 hour. Concentrated hydrochloric acid-methanol (1:11, 0.088 ml) was added thereto and the mixture was concentrated. The concentrate was subjected to silica gel column chromatography using chloroform-methanol (30:1) as an eluent. The resultant crystals were recrystallized from chloroform-hexane to give 312 mg of colorless, crystalline 2-octadecyl-2-(N-pentanoylamino)-1,3-propanediol.
