実験手順

2,6-Diamino-9-(β-D-ribofuranosyl)purine (50 g, 180 mmol) and sodium hydride (7 g) in DMF (1 L) were heated to boiling for 2 hr. Iodooctadecane (100 g) was added at 150° C. and the reaction mixture allowed to cool to RT. The reaction mixture was stirred for 11 days at RT. The solyent was evaporated and the residue purified by silica gel chromatography. The product was eluted with 5% MeOH/CH2Cl2. The appropriate fractions were evaporated to yield the product (11 g). 1H NMR (DMSO-d6) δ 0.84 (t, 3, CH2), 1.22 (m, 32, O--CH2 --CH2 --(CH2)16), 1.86 (m, 2, O--CH2CH2), 3.25 (m, 2, O--CH2), 3.93 (d, 1, 4'H), 4.25 (m, 1, 3'H), 4.38 (t, 1, 2' H), 5.08 (d, 1, 3'-OH), 5.48 (t, 1, 5'-OH, 5.75 (s, 2, 6-NH2), 5.84 (d, 1, 1'-H), 6.8 (s, 2, 2-NH2), and 7.95 (s, 1, 8-H).
