実験手順: 2.6 g of 5-fluorouracil was suspended in 20 ml of absolute dioxane and 10 ml of absolute pyridine, and 15 g of palmityl chloride was added to the suspension followed by heating at 80° C for 1 hour while stirring. After completion of the reaction, the solvent was removed under reduced pressure (25 mm Hg), and the residual solid was washed with hot hexane (50° C). Any insoluble matter in the hot hexane was recrystallized from benzene to obtain 4.0 g of 1-N-palmitoyl-5-fluorouracil in a yield of 54%. Melting Point: 98° C.

実験手順: To a refluxing mixture of 1.26 g of magnesium turnings, 15.5 ml of 1-chlorohexadecane, and 100 ml of anhydrous diethyl ether were added 0.5 ml of a 3.2M solution of methylmagnesium bromide in diethyl ether and 0.05 ml of ethyl bromide. The reaction mixture was refluxed for a period of 6 hours. A solution of 3.0 g of 4-[(tetrahydro-2H-pyran-2-yl)oxy]butanal in 10 ml of diethyl ether was added, and the reaction mixture refluxed for an additional hour.

The organic phase was dried over anhydrous sodium sulfate and concentrated to an oil. Flash chromatography of the oil utilizing 25% diethyl ether/petroleum ether yielded 4.8 g (70%) of 1-[(tetrahydro-2H-pyran-2-yl)oxy]eicosan-4-ol as a solid, mp 39°-43°.

実験手順: In a 250 ml capacity conical flask 13 g cetyl chloride (0.05 M), 3.5 g acrylamide (0.05 M) and 50 ml acetone were placed to obtain a clear solution. The solution was stirred with a magnetic needle at room temperature. 6.5 g anhydrous aluminium chloride (0.05 M) was added and the reaction mixture was stirred at room temperature. After 5 to 10 minutes of stirring, vigorous evolution of hydrogen chloride took place which ceased after about 5 minutes. Temperature of the reaction mixture was raised to 40 to 50° C. It was then cooled to room temperature and poured into 500 ml cold water. White product was precipitated. The product was isolated and purified by reprecipitation from acetone into cold water. to obtain a clear solution the reaction mixture was stirred at room temperature After 5 to 10 minutes of stirring Temperature of the reaction mixture was raised to 40 to 50° C It was then cooled to room temperature White product was precipitated The product was isolated purified by reprecipitation from acetone into cold water
