The title compound was prepared in a manner similar to Example 1 (Steps 1-8). N-[(but-3-en-1-yloxy)carbonyl]-L-norleucine was prepared according to the procedure used for [(4-pentenyloxy)carbonyl]-L-norleucine (Example 3), and was used in place of N-[(allyloxy)carbonyl]-L-norleucine. 1H NMR (500 MHz, MeOH-d4) ppm: 8.58 (s, 1H), 8.42 (s, 1H), 8.09 (m, 3H), 7.96 (d, 1H), 7.74 (m, 4H), 6.70 (d, J=15.2 Hz, 1H), 6.39 (m, 1H), 5.87 (m, 2H), 5.29 (d, 1H), 5.10 (d, 1H), 4.80 (m, 2H), 4.71 (m, 2H), 4.57 (t, 1H), 4.07 (m, 2H), 2.86 (dd, 1H), 2.70 (m, 1H), 2.55 (m, 1H), 2.48 (t, 1H), 2.17 (dd, 1H), 1.85 (m, 1H), 1.79-1.64 (m, 2H), 1.55-1.37 (m, 5H), 1.01 (t, 3H).
