反応手順

To 50 mg of 9-(1,3-dihydroxy-2-propoxymethyl)guanine in 5 ml of N,N-dimethylformamide were added 290 mg dicyclohexycarbodiimide and 300 mg of n-hexadecanoic acid and the solution was stirred at 50° C. for 50 hours. The compound was then precipitated in ice water. The water was extracted with methylene chloride (3×). The combined methylene chloride extracts were concentrated, then purified on preparative silica gel plates developed in 1:9 methanol:methylene chloride to yield 140 mg 9-(1,3-di-n-hexadecanoyloxy-2-propoxymethyl)guanine, m.p. 150°-154° C.
