실험 절차

In the same manner as described in Example 2-(5), L-serine benzyl ester (390 mg, 2.0 mmol) was acylated with (R)-3-heptanoyloxytetradecanoic acid (780 mg, 2.2 mmol) in the presence of EDC·MeI (745 mg, 2.5 mmol) in CH2Cl2 to afford 0.97 g (91%) of N-[(R)-3-heptanoyloxytetradecanoyl]-L-serine benzyl ester: mp 46-48° C.; 1H NMR (CDCl3) δ 0.88 (t, 6H, J=6.9 Hz), 1.1-1.7 (m, 28H), 2.30 (t, 2 H, J=7.7 Hz), 2.50 (d, 2H, J=5.8 Hz), 2.62 (t, 1H, J=6.0 Hz), 3.97 (m, 2H), 4.65 (m, 1H), 5.19 (m, 3H), 6.61 (d, 1H, J=6.9 Hz), 7.35 (br s, 5H).
