実験手順: Preparation of the starting compound for Examples 24 and 25: Under nitrogen, 42.9 g (170 mmol) of 11-bromo-1-undecanol are added at 80° C. to a solution of 20.3 g (50 mmol) of 2,4,6-tris(2,4-dihydroxyphenyl)-1,3,5-triazine, 9.3 g (141 mmol) of potassium hydroxide and 150 ml of diglyme. The mixture is heated at 100° C. for 16 hours and filtered while hot, and the filtrate is cooled to 0° C. The crystallized solid is filtered off, pressed and dried for 48 hours under reduced pressure (60 mmHg, 70° C.), giving 24.3 g (53% yield) of 2,4,6-tris[2-hydroxy-4-(11-hydroxyundecyloxy)phenyl]-1,3,5-triazine as a pale yellow, resin-like solid. Preparation of the starting compound for Examples 24 and 25 filtered while hot, and the filtrate is cooled to 0° C The crystallized solid is filtered off dried for 48 hours under reduced pressure (60 mmHg, 70° C.)

実験手順: Under nitrogen, 32.4 g (128 mmol) of 11-bromo-1-undecanol are added at 80° C. to a solution of 20.0 g (54 mmol) of 2-phenyl-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine, 6.6 g (109 mmol) of potassium hydroxide and 150 ml of diglyme. The mixture is heated at 100° C. for 14 hours and filtered while hot, and the filtrate is cooled to 0° C. The solid which crystallizes therefrom is filtered off, pressed and dried for 24 hours under reduced pressure (60 mmHg, 60° C.), giving 27.6 g (72% yield) of 2-phenyl-4,6-bis[2-hydroxy-4-(11-hydroxyundecyloxy)phenyl]-1,3,5-triazine as a pale yellow solid of melting point 126°-135° C. filtered while hot, and the filtrate is cooled to 0° C The solid which crystallizes therefrom is filtered off dried for 24 hours under reduced pressure (60 mmHg, 60° C.)

実験手順: 11-Bromoundecan-1-ol (m.p. 45°-48° C. ) is reacted with sodium hexanolate and the syrupy product obtained is reacted with phosphorus tribromide in the presence of pyridine. The structure of the oil obtained is confirmed by mass spectroscopy as being 11-bromoundecyloxyhexane. This bromo compound is reacted with methyl β-mercaptopropionate in sodium methylate solution and the oil obtained is then reduced with lithium aluminium hydride to give 3-(11-hexyloxyundecylthio)-propanol; m.p. 27°-29° C. Phosphorylation and choline ester formation in a manner analogous to that described in Example 20C gives the desired end product in a yield of 55% of theory in the form of a monohydrate which sinters at 98° C. and decomposes at 226°-229° C. the syrupy product obtained The structure of the oil obtained the oil obtained
